Subject: [PATCH RESEND 1/2] MIPS: Replace CONFIG_MIPS64 and CONFIG_MIPS32_R2

From: Paul Bolle <pebolle@...cali.nl>

Commit 597ce1723e0f ("MIPS: Support for 64-bit FP with O32 binaries")
introduced references to two undefined Kconfig macros. CONFIG_MIPS32_R2
should clearly be replaced with CONFIG_CPU_MIPS32_R2. And CONFIG_MIPS64
should apparently be replaced with CONFIG_64BIT.
