plat: arm: refactor GIC initialization
All platforms (except STM32MP1) follow the same pattern during GIC
initialization: get virtual addresses for distributor (and optionally,
for CPU interface), check that they are not NULL, call either
gic_init() or gic_init_base_addr().
We can move most of this logic into gic_init_base_addr(), while
platform-specific code will supply only base physical addresses for
distributor and CPU interface. This will simplify and align platform
code.
ST32MP1 had more complex logic, as it used io_pa_or_va_secure() to get
MMIO range addresses. However, as main_init_gic() called
assert(cpu_mmu_enabled()), there is no sense in using
io_pa_or_va_secure(), because we already ensured that VA will be
always used. Thus assert() call was moved to gic_init_base_addr(), and
STM32MP1 were aligned with other platforms.
