Subject[PATCH 1/2] sh: intc: Confine SH_INTC to platforms that need it
Date
Currently the sh-intc driver is compiled on all SuperH and
non-multiplatform SH-Mobile platforms, while it's only used on a limited
number of platforms:
- SuperH: SH2(A), SH3(A), SH4(A)(L) (all but SH5)
- ARM: sh7372, sh73a0

Drop the "default y" on SH_INTC, make all CPU platforms that use it
select it, and protect all sub-options by "if SH_INTC" to fix this.
