realtek: rtl931x: drop LINKER_LOAD_ADDRESS bypass

RTL931x kernel builds were patched to bypass the LINKER_LOAD_ADDRESS
parameter, and hardcode it to 0x80220000. This doesn't make much sense,
since value of LINKER_LOAD_ADDRESS, load-ld, only appears to be a copy
of load-y, adjusted to the linker's taste.

Dropping the hacks for bypassing LINKER_LOAD_ADDRESS results in a kernel
that actually starts booting on an RTL9313 (Netgear MS510TXM), but
currently still hangs when the kernel switches timers.
