ARM: net: bpf: improve 64-bit load immediate implementation
Rather than writing each 32-bit half of the 64-bit immediate value
separately when the register is on the stack:
movw r6, #45056 ; 0xb000
movt r6, #60979 ; 0xee33
str r6, [fp, #-44] ; 0xffffffd4
mov r6, #0
str r6, [fp, #-40] ; 0xffffffd8
arrange to use the double-word store when available instead:
movw r6, #45056 ; 0xb000
movt r6, #60979 ; 0xee33
mov r7, #0
strd r6, [fp, #-44] ; 0xffffffd4
