arm: smp: Concentrate non-PSCI logic in Versatile Express module

We only keep the non-PSCI CPU hotplug support around for the sake of
old Versatile Express boards/models. No new boards will be accepted that
do not support the PSCI standard. Therefore, concentrate all functions
that were once considered reusable in the smp-vexpress module, folding
them into their only callers.

Log Message:
-----------
arm: Fix arm_page_table_empty

The size of a pt_entry_t is a reference to an entry, not the entry type
itself. So we were calculating with an entry size of 4 instead of 8,
overrunning the table during empty checks. This specifically caused
page leakages during cell destruction.

Log Message:
-----------
arm: Account for errors during irqchip cell_init

The cell_init callback of GICv2 should report the result of the mapping
request, thus needs a channel to return an error code. Extend the call
chain accordingly.

Log Message:
-----------
arm: Use paging_create instead of arch_map_memory_region for GICv2 mapping

It's actually simpler to invoke paging_create directly instead of
preparing arguments for arch_map_memory_region first.

Log Message:
-----------
arm: Unmap virtual GIC on cell destruction

This fixes a leak on cell destruction because we left the GICv2 mapped,
thus didn't free all paging structures. This also means we need to run
the irqchip cleanup before the cell MMU destruction.

Log Message:
-----------
arm: Use more panic_printk for fatal error messages

Fatal errors that will leave CPUs unusable and may occur in parallel on
multiple CPUs should be reported via panic_printk to maintain
readability of the output. Adjust some locations for unexpected HYP
exits and failing PSCI_CPU_OFF.

Log Message:
-----------
core, inmates: Move \r injection into console_write / arch_dbg_write

This moves the injection of \r on \n into the console_write and
arch_dbg_write implementations, causing some minor duplication but also
fixing injection for %s strings. Furthermore, this allows to skip the
injection for consoles the may not need it.
