Drop all instances of such selection from non-arch code.

Mark pointed out that ep93xx doesn't select GENERIC_IRQ_MULTI_HANDLER,
and that this removal breaks it. I've added the patch below before
this one to address the issue.
Thanks,
M.

Subject: [PATCH] ARM: ep93xx: Select GENERIC_IRQ_MULTI_HANDLER directly
ep93xx currently relies of CONFIG_ARM_VIC to select
GENERIC_IRQ_MULTI_HANDLER. Given that this is logically a platform
architecture property, add the selection of GENERIC_IRQ_MULTI_HANDLER
at the platform level.
Further patches will remove the selection from the irqchip side.
