Currently there are garbled messages from OP-TEE due to
assumption that platform clock is always 700MHz. This is
not correct as LX2 supports variable platform frequency.
It could be one of the 600, 650, 700, 750 Mhz based on
the RCW configuration.
Ideally OPTEE should read RCW registers from Global Utilities
Register block and derive the uart clock based on platform pll
frequency. But there is no need for this as Baud Rate is already
configured in PL011 by the previous boot stages in TF-A.
This fix calls pl011_init() with zero for baud rate => It won't be
reinitalized in OP-TEE.
