plat-synquacer: use cpu_spin_lock_xsave() and friend

Change RNG PTA implementation for synquacer platform to use helper
functions cpu_spin_lock_xsave() and cpu_spin_unlock_xrestore() instead
of calling thread_mask_exceptions()/cpu_spin_lock() pair and
thread_set_exceptions()/cpu_spin_unlock() pair. This makes the
implementation more consistent.

No functional change.

core_mmu: fix phys_to_virt() to check length

phys_to_virt() function without length parameter doesn`t
always have ability to find the correct mapping for
requested physical address. This is because physical
address can be mapped in the same time in different virtual
regions with different length. So the first found region
which contains the requested physical address possibly
doesn`t have enough mapped data. This is fixed by adding
the length parameter to phys_to_virt() function. Length
parameter can be set to 1 if caller knows that requested
(pa + len) doesn`t cross mapping granule boundary.

core_mmu_get_va() and io_pa_or_va() functions now are
take length parameter too as they based on phys_to_virt()
in case of MMU enabled.
