ppc: Rework POWER7 & POWER8 exception model
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
This patch fixes the current AIL implementation for POWER8. The
interrupt vector address can be calculated directly from LPCR when the
exception is handled. The excp_prefix update becomes useless and we
can cleanup the H_SET_MODE hcall.

[clg: Removed LPES0/1 handling for HV vs. !HV
Fixed LPCR_ILE case for POWERPC_EXCP_POWER8 ]

[dwg: This was written as a cleanup, but it also fixes a real bug
where setting an alternative interrupt location would not be
correctly migrated]
