Override the switch_to_hypervisor function to switch cpu to hypervisor
mode using the available ROM code hook early in the boot phase before
the boot loader checks for HYP mode.

On some of the SoCs one cannot enable hypervisor mode directly from the
u-boot because the ROM code puts the chip to supervisor mode after it
jumps to boot loader. Hence introduce a weak function which can be
overridden based on the SoC type and switch to hypervisor mode in a
custom way.

Cache configuration methods is different for LPAE and non-LPAE cases.
Hence the bits and the interpretaion is different for two cases.
In case of non-LPAE mode short descriptor format is used and we need
to set Cache and Buffer bits.
In the case of LPAE the cache configuration happens via MAIR0 lookup.

The SPL and U-Boot proper may use different initial stack
locations, which are configured via CONFIG_SPL_STACK and
CONFIG_SYS_INIT_SP_ADDR defines. The lowlevel_init.S
code needs to handle this in the same way as crt0.S
Without this fix, setting the U-Boot stack location to some
place, which is not safely accessible by the SPL (such as
the DRAM), causes a very early SPL deadlock.

Depending on the boot media, different images are needed

For AM33xx devices additional image types are needed for
