plat/arm: Support direct Linux kernel boot in AArch32
This option allows the Trusted Firmware to directly jump to Linux
kernel for aarch32 without the need of an intermediate loader such
as U-Boot.
Similar to AArch64 ARM_LINUX_KERNEL_AS_BL33 only available with
RESET_TO_SP_MIN=1 as well as BL33 and DTB are preloaded in memory.
