(refer "mx7ulp_evk: Change APLL and its PFD0 frequencies"), we set DDR

APLL PFD0 -> DDR CLK -> NIC0 -> NIC1 -> LCDIF clock

To reduce the impact to entire system, the NIC0_DIV and NIC1_DIV are kept,
so the divider 14 is calculated as:
14 = (NIC0_DIV + 1) * (NIC1_DIV + 1) * (LCDIF_PCC_DIV + 1)

NIC0_DIV:      1

We set MULT to 20, NUM to 4 and DENOM to 2, to get final 22 multiplier. But according to the RM,
the NUM should always be less than the DENOM. So our setting violates the rule.

is 318.9888Mhz, which also meet the DDR requirement.

BCB contains two data structures, Firmware Configuration Block(FCB)
and Discovered Bad Block Table(DBBT). FCB has nand timings,
DBBT search area, page address of firmware.

On summary, nandbcb update will
- erase the entire partition
- create BCB by creating 2 FCB/DBBT block followed by
  1 FW block based on partition size and erasesize.
- fill FCB/DBBT structures
- write FW/SPL on FW1
- write FCB/DBBT in first 2 blocks

for nand boot, up on reset bootrom look for FCB structure in
first block's if FCB found the nand timings are loaded for
further reads. once FCB read done, DTTB will load and finally
