ARM: OMAP2+: Fix sar_base inititalization for HS omaps

Browse source 
[ Upstream commit fe27f16794 ]

HS omaps use irq_save_secure_context() instead of irq_save_context()
so sar_base will never get initialized and irq_sar_clear() gets called
with a wrong address for HS omaps from irq_restore_context().

Starting with commit f4b9f40ae9 ("ARM: OMAP4+: Initialize SAR RAM
base early for proper CPU1 reset for kexec") we have it available,
and this ideally would been fixed with that commit already.

Fixes: f4b9f40ae9 ("ARM: OMAP4+: Initialize SAR RAM base early for
proper CPU1 reset for kexec")
