efi_loader: Rename EFI_RUNTIME_{TEXT, DATA} to __efi_runtime{, _data}

Compiler attributes are more commonly __foo style tags rather than big
upper case eye sores like EFI_RUNTIME_TEXT.

Simon Glass felt quite strongly about this, so this patch converts our
existing defines over to more eye friendly ones.

arm: Provide common PSCI based reset handler

Most armv8 systems have PSCI support enabled in EL3, either through
ARM Trusted Firmware or other firmware.

On these systems, we do not need to implement system reset manually,
but can instead rely on higher level firmware to deal with it.

The exclude list seems excessive right now, but NXP is working on
providing an in-tree PSCI implementation, so that all NXP systems
can eventually use PSCI as well.

arm: Disable HVC PSCI calls by default

All systems that are running on armv8 are running bare metal with firmware
that implements PSCI running in EL3. That means we don't really need to expose
the hypercall variants of them.

This patch leaves the code in, but makes the code explicit enough to have the
compiler optimize it out. With this we don't need to worry about hvc vs smc
calling convention when calling psci helper functions.
