Address 0x8880_0000 is reserved for M4 image on imx8q, which
leaves limited memory region for the malloc pool. The avb
will consume much heap memory to verify the kernel and dtbo
image, memory conflicts may happen as the kernel/dtbo image
size is getting larger.
As the avb will load kernel/dtbo in every avb_slot_verify(), but
will only free the memory after both slots are checked(if needed).
And for trusty enabled platforms, extra heap memory will be used
to do the hash calculation.
This commit will free the slot memory once it's marked as unbootable
and will use fixed memory started from CONFIG_FASTBOOT_BUF_ADDR to
help store the data to do the hash calculation. With above change,
we get a chance to decrease the malloc pool size.
Test: boot on imx8qxp and imx8mn.

Add configs to support evk_imx8mm 4GB DDR board. The 4GB DDR will
be split into two banks, one is 3GB (0x4000_0000~0xffff_0000) and
another is 1GB(0x1_0000_0000~0x1_4000_0000).
Test: build and boot with or without trusty.

CONFIG_SYSTEM_RAMDISK_SUPPORT
system can't enable CONFIG_SYSTEM_RAMDISK_SUPPORT in non-AB system.
boot.img have normal boot kernel and recovery ramdisk.
So ota can't update boot.img in both normal boot and recovery mode.

CAAM was enabled on imx8m by default in commit 9963299
(MLK-18703: crypto: caam: Add TRNG init function call),
this will cause errors when try to access RPMB.
Disable CAAM on imx8m because we don't need it on Android now.
Test: build and boot ok on imx8m_evk and imx8mm_evk.

We can get the bootimage SD/MMC offset at runtime according to the SOC type and
version. No need to use CONFIG_BOOTLOADER_OFFSET_33K and CONFIG_BOOTLOADER_OFFSET_32K
any longer, so remove them.
