fix: msys: Fix the dead-lock of mvBoardTclkGet with I2C.
Tclk routine was dependent on I2C transaction, which needs Tclk.
this created a dead-lock, which lead to always using DB board as default
Board ID.
to prevent dead-lock, separated Tclk get flow from U-Boot & Linux:
U-Boot Flow:
------------
according to MV_MSYS definition (exists only in MSYS platform U-Boot),
Skip reading FamilyIdGet to derrive Tclk, and use static Tclk for MSYS
platforms (AXP-AMC uses different u-boot version:2011.12)
Linux flow:
-----------,
previous flow remains: FamilyIdGet can use BoardIDGet,
since Board id is not being read from TWSI, but passed from
U-Boot tags instead
