ARMv8: add the secure monitor firmware framework
This framework is introduced for ARMv8 secure monitor mode firmware.
The main functions of the framework are, on EL3, verify the firmware,
load it to the secure memory and jump into it, and while it returned
to U-Boot, do some necessary setups at the 'target exception level'
that is determined by the respective secure firmware.
So far, the framework support only FIT format image, and need to define
the name of which config node should be used in 'configurations' and
the name of property for the raw secure firmware image in that config.
The FIT image should be stored in Byte accessing memory, such as NOR
Flash, or else it should be copied to main memory to use this framework.

thunderx: Move mmu table into board file
The MMU range table can vary depending on things we may only find
out at runtime. While the very simple ThunderX variant does not
change, other boards will, so move the definition from a static
entry in a header file to the board file.

arm64: Make full va map code more dynamic
The idea to generate our pages tables from an array of memory ranges
is very sound. However, instead of hard coding the code to create up
to 2 levels of 64k granule page tables, we really should just create
normal 4k page tables that allow us to set caching attributes on 2M
or 4k level later on.
So this patch moves the full_va mapping code to 4k page size and
makes it fully flexible to dynamically create as many levels as
necessary for a map (including dynamic 1G/2M pages). It also adds
support to dynamically split a large map into smaller ones when
some code wants to set dcache attributes.
With all this in place, there is very little reason to create your
own page tables in board specific files.

arm64: Disable TTBR1 maps in EL1
When running in EL1, AArch64 knows two page table maps. One with addresses
that start with all zeros (TTBR0) and one with addresses that start with all
ones (TTBR1).
arm64: Disable TTBR1 maps in EL1
When running in EL1, AArch64 knows two page table maps. One with addresses
that start with all zeros (TTBR0) and one with addresses that start with all
ones (TTBR1).
In U-Boot we don't care about the high up maps, so just disable them to ensure
we don't walk an invalid page table by accident.
