JEDEC spec requires the clocks to be stable before deasserting reset
signal for RDIMMs. Clocks start when any chip select is enabled and
clock control register is set. This patch also adds the interface to
toggle memory reset signal if needed by the boards.

QIXIS FPGA is accessable via both i2c and flash controller.
Only flash controller access is supported.
Add support of i2c based access. It is quite useful in the scenario
where either flash controller path is broken or not present.

Remove #ifdef so that "qixis dump" command is always available
Add "qixis_reset switch" command to dump switch settings
Qixis doesn't have 1:1 switch mapping. We need to reverse engineer from
registers to figure out switch settings. Not all bits are available.

QIXIS FPGA's QIXIS Tag Access register (QTAG) defines TAG, VER, DATE, IMAGE
fields. These fields have FPGA build version, image name and build date
information.
Add support to parse these fields to have complete FPGA image information.

According to new QIXIS system definition, update QIXIS registers set
to add present2 register instead of obsolete ctl_sys2.

QIXIS FPGA layout defines the address of registers but The actual register bit
implementation is board-specific,
So avoid use of magic numbers as it may vary across different boards's QIXIS
FPGA implementation.
Also, Avoid board specific defines in common/qixis.h
