Marek Vasut c3c082aa43 arm: Introduce current_pl() on ARM32 and compatibility current_el() ...

The ARM32 has PLx Privilege Levels instead of Exception Levels present
on ARM64. Introduce current_pl() function which reports the current PL
on ARM32.

Introduce current_el() for ARM32 as well and current_pl() for ARM64
which each call the other matching function. This is mainly mean to
allow code like this to compile and retain compile time code coverage:

if (IS_ENABLED(CONFIG_ARM64) && current_el() != 3) { ... }
if (!IS_ENABLED(CONFIG_ARM64) && current_pl() != 0) { ... }
