nb/intel/e7505: Leave ROM as un-cacheable in postcar
Collected timestamps indicate LZMA decompression of ramstage
is 4x slower when ROM is marked WP-cacheable, in contrast to
having ROM as US. A simple copy WP->WB with uncompressed
ramstage also appeared to be twice as slow as UC->WB copy.
It should be noted that if POSTCAR_STAGE was removed from build,
un-lzma takes 130 seconds instead of 45 milliseconds.
