arm: mmu: Fix truncated 40-bit physaddr (LPAE)

Wrong type for parameter 'phys' caused adress to be truncated to 32-bits,
causing iotable_init() to produce wrong MMU mappings on LPAE system.

axxia: Fixed earlyprintk

Add static mapping of the UART registers for CONFIG_DEBUG_LL. Also depends on
commit 2f409a to fix a bug with LPAE and static mappings.

LSI: Fix axm55xx Distributed Interrupt Driver

This patch modifies the axxia-gic.c driver to use its own internal
RPC mechanism to run functions on remote clusters. Previously, the driver
would use smp_call_function_single() with illegal interrupt re-enables.

axxia: Define arch_is_coherent()

By defining arch_is_coherent() == 1, we can avoid unnecessary cache maintenance
operations and the dma_alloc_coherent() will return normal memory.

LSI AXM55xx: Enable multi-cluster wfe/sev

By default, the system does not enable the use of ARM wfe/sev instructions
across clusters, which breaks things like arch_spin_lock. This patch enables
this feature.

LSI AXM55xx: Disable use of wfe/sev in arch_spin_lock

By default, the system does not enable the use of ARM wfe/sev instructions
across clusters, which breaks things like arch_spin_lock. The previous
solution to enable wfe/sev to work across clusters still resulted in CPU
stalls. This patch instead removes the use of wfe/sev in arch/arm/include/
asm/spinlock.h altogether.
