We have moved the busy-wait loop out of drivers and into the uclass. This
means that we must reset the watchdog when busy-waiting.
Note: some drivers may still have a busy-wait even with driver model, as

The EDMA3 controller’s primary purpose is to service data transfers
that you program between two memory-mapped slave endpoints on the device.
Typical usage includes, but is not limited to the following:
- Servicing software-driven paging transfers (e.g., transfers from external
memory, such as SDRAM to internal device memory, such as DSP L2 SRAM)
- Servicing event-driven peripherals, such as a serial port
- Performing sorting or sub-frame extraction of various data structures
- Offloading data transfers from the main device DSP(s)
- See the device-specific data manual for specific peripherals that are
accessible via the EDMA3 controller

The keystone_nav driver is general driver intended to be used for
working with queue manager and pktdma for different IPs like NETCP,
AIF, FFTC, etc. So the it's API shouldn't be named like it works only
with one of them, it should be general names. The names with prefix
like netcp_* rather do for drivers/net/keystone_net.c driver. So it's
good to generalize this driver to be used for different IP's and
delete confusion with real NETCP driver.
The current netcp_* functions of keystone navigator can be used for
other settings of pktdma, not only for NETCP. The API of this driver
is used by the keystone_net driver to work with NETCP, so net driver
also should be corrected. For convenience collect pkdma

Adjust the driver so that leaf functions take a pointer to the serial port
register base. Put all the global configuration in the init function, and
use the same settings from then on.
This makes it much easier to move to driver model without duplicating the
code, since with driver model we use platform data rather than global
settings.
The driver is compiled with either the CONFIG_PL010_SERIAL or
CONFIG_PL011_SERIAL option and this determines the uart type. With driver
model this needs to come in from platform data, so create a new
CONFIG_PL01X_SERIAL config which brings in the driver, and adjust the
driver to support both peripheral variants.
