parisc: Merge millicode routines via linker script

When compiling the 4.13-rc kernel I got those linker errors:
libgcc2.c:(.text+0x110): relocation truncated to fit: R_PARISC_PCREL22F against symbol `$$divU'

	defined in .text.div section in /usr/lib/gcc/hppa64-linux-gnu/4.9.2/libgcc.a(_divU.o)

hppa64-linux-gnu-ld: /usr/lib/gcc/hppa64-linux-gnu/4.9.2/libgcc.a(_moddi3.o)(.text+0x174): cannot reach $$divU

Avoid such errors by bundling the millicode routines in the linker script.
