This commit enables the RK3399 HDMI TX, which is very similar to the
one found on the RK3288. As requested by Simon, this splits the HDMI
driver into a SOC-specific portion (rk3399_hdmi.c, rk3288_hdmi.c) and
a common portion (rk_hdmi.c).
Note that the I2C communication for reading the EDID works well with
the default settings, but does not with the alternate settings used on
the RK3288... this configuration aspect is reflected by the driverdata
for the RK3399 driver.
Having some sort of DTS-based configuration for the regulator
dependencies would be nice for the future, but for now we simply use
lists of regulator names (also via driverdata) that we probe.

To prepare for the addition of RK3399 HDMI support, the HDMI driver is
refactored and broken into a chip-specific and a generic part. This
change adds the internal interfaces, makes common/reusable functions
externally visible and splits the RK3288 driver into a separate file.
For the probing of regulators, we reuse the infrastructure created
during the VOP refactoring... i.e. we simply call into the helper
function defined for the VOP.

To prepare for adding the RK3399 VOP driver (which shares most of its
registers and config logic with the RK3228 VOP), this change refactors
the driver and splits the RK3288-specific driver off.
The changes in detail are:
- introduces a data-structure for chip-specific drivers to register
features/callbacks with the common driver: at this time, this is
limited to a callback for setting the pin polarities (between the
VOP and the encoder modules) and a flag to signal 10bit RGB
capability
- refactors the probing of regulators into a helper function that
can take a list of regulator names to probe and autoset
- moves the priv data-structure into a (common) header file to be
used by the chip-specific drivers to provide base addresses to
the common driver
- uses a callback into the chip-specific driver to set pin polarities
(replacing the direct register accesses previously used)
- splits enabling the output (towards an encoder) into a separate
help function withint the common driver

This adds a simple driver for reading the efuse block of the RK3399.
It should be easy enough to add drivers for other devices (e.g. the
RK3328, RK3368, etc.) by passing the device details via driver_data.
Unlike the kernel driver (using the nvmem subsystem), we don't expose
the efuse as multiple named cells, but rather as a linear memory that
can be read using misc_read(...).
The primary use case (as of today) is the generation of a 'serial#'
(and a 'cpuid#') environment variable for the RK3399-Q7 (Puma)
system-on-module.
Note that this adds a debug-only (i.e. only if DEBUG is defined)
command 'rk3399_dump_efuses' that dumps the efuse block's content.
N.B.: The name 'rk3399_dump_efuses' was intentionally chosen to
include a SoC-name (together with a comment in the function) to
remind whoever adds support for additional SoCs that this
function currently makes assumptions regarding the size of the
fuse-box based on the RK3399. The hope is that the function is
adjusted to reflect any changes resulting from generalising the
driver for multiple SoCs and is then renamed.

This deassert counter allow to manage "shared" reset lines
encountered in some specific case. On STiH410 SoC, DWC3,
EHCI and OHCI are all using a respective PHY, but all of
these PHYs shared a "global" reset.
Currently, during command "usb stop", all host controller are
stopped (XHCI, EHCI and OHCI). XHCI is first shutdowned, which
means that PHY global reset is asserted. Then EHCI is shutdowned,
but its PHY reset has already been asserted which make handshake()
call failed in ehci_shutdown().
This counter allows to really assert a reset lines only when the
