Refact the lpddr4 init flow on i.MX8MM EVK board. board level only need

Signed-off-by: Bai Ping <ping.bai@nxp.com>

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.

"fastboot reboot bootloader" fails to transmit "OKAY" back to host on
imx8qm because fastboot_tx_write_str() will dequeue the IN request
first before queue it, cdns3 usb driver will always invoke the complete
callback in dequeue, so if we are going to do_reset() in the complete
callback, the device will reboot before we can transmit "OKAY" back to
host in queue.
Check the request status in dequeue first before invoke the complete
callback, this is basically ported from kernel.

Test: No error messages when run "fastboot reboot bootloader" on
      imx8qm_mek.

In optee enabled defconfig, the trust zone is enabled in DCD. On iMX6UL/ULL, there
is IC limitation that LCDIF master access can only be non-secure, because PL301
hard code the m_3/4/5 to non-secure masters. It causes LCDIF fails to fetch data
from memory.

This patch adds a workaround to change trust zone Region 0 attribute to allow both secure
and non-secure read/write. So it permits the LCDIF master access to memory.
Since optee will configure Region 0 by itself, this should not introduce problem to optee.
