[MIPS] Remove TARGET_ASM_FUNCTION_RODATA_SECTION 

Since 'Remove obsolete IRIX 6.5 support' [1] we only use
gp-relative jump-tables for PIC code. We can fall back to
default behaviour for asm_function_rodata_section.

/* Implement TARGET_ASM_FUNCTION_RODATA_SECTION.
The complication here is that, with the combination TARGET_ABICALLS
&& !TARGET_ABSOLUTE_ABICALLS && !TARGET_GPWORD, jump tables will use
absolute addresses, and should therefore not be included in the
read-only part of a DSO. Handle such cases by selecting a normal
data section instead of a read-only one. The logic apes that in
default_function_rodata_section. */
