Abhishek Shah 3a63e8564e soc: arm: viper: Fix callee saved register corruption in el3 init
x19 is callee saved register. z_arch_el3_plat_init being a callee,
it should save it before using it. However, at this point, stack
has not been setup. So, let's just use x20 instead which is not
being used caller yet. This bug was causing VBAR_EL1 corruption,
but since [10:0] bits are reserved, bug was hidden.
