According to TRM for i.MX8M Nano and Plus, GPR10 register contains lock
bit for TZASC_ID_SWAP_BYPASS bit. This bit is required to be set in
order to avoid AXI bus errors when GPU is enabled on the platform.
TZASC_ID_SWAP_BYPASS bit is alread set for all imx8m applicable
derivatives, but is missing a lock settings to be applied.
Set the TZASC_ID_SWAP_BYPASS_LOCK bit for those derivatives which have
it implemented.
Since we're here, provide also names to bits from TRM instead of using
BIT() macro in the code.

Add some SOC level codes and build configurations to use HAB lib for
CONFIG_IMX_HAB (secure boot), like adding the SEC_CONFIG fuse, enable
fuse driver, CAAM clock function, and add CAAM secure RAM to MMU table.
The FSL_CAAM is temporally not enabled for iMX8M when CONFIG_IMX_HAB is set,
because we don't need the CAAM driver for SPL.

The value of Unique ID in uboot and kernel is different for iMX8MP:
serial#=02e1444a0002aaff
root@imx8mpevk:/sys/devices/soc0# cat soc_uid
D699300002E1444A
The reason is that Fuse Addresses of Unique ID of iMX8MP are 0x420 and
0x430.

the DRAM Controller in i.MX8MP will support a feature called "Inline ECC".
This is supported for all 3 supported DRAM technologies (LPDDR4, DDR4 and
DDR3L). When this feature is enabled by software, the DRAM Controller
reserves 12.5% of DRAM capacity for ECC information, and presents only
the non-ECC portion (lower 87.5% of the installed capacity of DRAM) to
the rest of the SoC.
The DRAM memory can be divided into 8 regions so that if a use case only
requires ECC protection on a subset of memory, then only that subset of
memory need support inline ECC. If this occurs, then there is no
performance penalty accessing the non-ECC-protected memory (no need to
access ECC for this portion of the memory map). This is all configured
with the DRAM Controller.

For ARM core clock, there are two input branches, and can select via mux:
one from ARM PLL directly, second from CCM A53 clock root.
Currently we are using second branch. But IC confirmed the CCM A53 root
signoff timing is 1Ghz, so we should switch to input from ARM PLL directly.
This patch fixes the CORE SEL slice configuration and switch ARM clock
to ARM PLL.

In cases when the same SPL should run on boards with i.MX8MM, that
differ in DDR configuration, it is necessary to try different
parameters and check if the training done by the firmware suceeds or
not.
Therefore we return the DDR training/initialization success to the
upper layer in order to be able to retry with different settings if
necessary.
