[PATCH] arm64/crypto: remove non-standard notation

[Nick Desaulniers]

It seems that:
ldr q8, =0x30000000200000001

is a GNU as convience notation for:
ldr q8, .Lconstant
.Lconstant
.word 0x00000001
.word 0x00000002
.word 0x00000003
.word 0x00000000

based on this comment in binutils' source [0]. I've asked for this
non-standard convience notation to be added to other assemblers [1], but
until then, we can remove it and get equivalent disassembly:

before:
00000000000009d4 <neon_aes_ctr_encrypt>:
...
     a48:       9c000ac8        ldr     q8, ba0 <neon_aes_ctr_encrypt+0x1cc>
...
     ba0:       00000001        .word   0x00000001
     ba4:       00000002        .word   0x00000002
     ba8:       00000003        .word   0x00000003
     bac:       00000000        .word   0x00000000

after:

00000000000009d4 <neon_aes_ctr_encrypt>:
...
     a48:       9c000aa8        ldr     q8, b9c <neon_aes_ctr_encrypt+0x1c8>
...
     b9c:       00000001        .word   0x00000001
     ba0:       00000002        .word   0x00000002
     ba4:       00000003        .word   0x00000003
     ba8:       00000000        .word   0x00000000
