MIPS: remove MSA macro recursion
commit a3a49810c55e3489dfb5d72a9b2e41ab1db9ffb9 upstream.
Recursive macros made the code more concise & worked great for the
case where the toolchain doesn't support MSA. However, with toolchains
which do support MSA they lead to build failures such as:
arch/mips/kernel/r4k_switch.S: Assembler messages:
arch/mips/kernel/r4k_switch.S:148: Error: invalid operands `insert.w $w(0+1)[2],$1'
arch/mips/kernel/r4k_switch.S:148: Error: invalid operands `insert.w $w(0+1)[3],$1'
arch/mips/kernel/r4k_switch.S:148: Error: invalid operands `insert.w $w((0+1)+1)[2],$1'
arch/mips/kernel/r4k_switch.S:148: Error: invalid operands `insert.w $w((0+1)+1)[3],$1'
...
Drop the recursion from msa_init_all_upper invoking the msa_init_upper
macro explicitly for each vector register.
