[v1][PATCH 1/1] powerpc/ppc64: rename SOFT_DISABLE_INTS with RECONCILE_IRQ_STATE

[Tiejun Chen <tiejun.chen@windriver.com>]

The SOFT_DISABLE_INTS seems an odd name for something that updates the
software state to be consistent with interrupts being hard disabled, so
rename SOFT_DISABLE_INTS with RECONCILE_IRQ_STATE to avoid this confusion.

Ben,

Looks currently RECONCILE_IRQ_STATE is our better choice as we discussed :)
