Update the ddrc Qos setting for B1 to align with B0'ssetting.
Correct the initial clock for dram_pll. This setting will be
overwrite before ddr phy training. Although there is no impact
on the dram init, we still need to correct it to eliminate
confusion.

Sometimes, SPL need to pass the trained FSP drate to ATF
if DDR PHY bypass mode is not enabled. So add a fsp_table
to pass these info to ATF. additionally, add more clock
frequency point config to support for code reuse for i.MX8MQ.

Optimize the DDR4 init flow. Split the common flow
with the DDR specific timing config. So the common
flow can be reused.

For LPDDR4 or DDR4, the ddr phy train flow is the same.
So rename the 'lpddr4_ddrphy_train.c' to 'ddrphy_train.c'.
make it more common for reuse and move it to driver/ddr/imx8m/.

Android build use different tool chain(gcc 4.9) with yocto(gcc 6.2),
'for' loop initial declarations are not supported in C90, define the
variable first before use it.
Test: build pass for imx8mm_evk.

the dram init is board related. But there is still some common
part can be reused on different board. The basic flow is common
for all the board. only the DDRC and DDR PHY config register setting
is different on different board. So extract the LPDDR4 init common
flow to make it more generic. baord level only need to provide
the DDRC and PHY config register parameter to the common code to finish
the dram init.
the same method can be use for DDR4. will be added later.
