eb46ee98bc mips/cache: Add missing nop's in delay slots
Lack of them causes random instructions to be executed before the
jump really happens.

eecdbebc84 Remove mips_attributes.
mips_attributes was introduced to work around clang problems with
-msoft-float. Those problems are now fixed and moreover .gnu_attributes
itself is unportable and creates problem with clang.

Revert "mips: Fix soft-float handling."

This partially reverts commit 6a4ecd276e.

6a4ecd276e mips: Fix soft-float handling.
Add -msoft-float alongside clang arguments to specify ABI.
Specify ABI in asm files explicitly.
This trigers asm warning due to gcc failing to propagate -msoft-float
but it's tolerable.

0d8f04cd83 Remove -march=mips3 from TARGET_CCASFLAGS as it creates linking problem
when rest of GRUB is compiled for hisher stepping. Instead use
	.set mips3/.set mips1 around cache and sync opcodes.
