frv: clean up linker script using new linker script macros.

Browse Source 
This is largely a straightforward conversion. The patch results in
fewer output sections, and some data being reordered, but should have
no functional impact.

Also, note that this patch moves some data (namely, init_task and
cacheline-aligned) inside [_sdata,_edata].

Because frv already builds using -ffunction-sections -fdata-sections,
we can't use BSS_SECTION or RW_DATA_SECTION yet, since they do not
currently include the required .bss.* and .data.* sections.
