MIPS: SB1: Remove support for Pass 1 parts.
Pass 1 parts had a number of significant erratas and were only available in small numbers and under NDA. Full support also required the use of a special toolchain that kept branches properly aligned. These workarounds were never upstreamed and the only toolchain known to have them is Montavista's GCC 3.0-based toolchain which completly obsoleted if not useless these days. So now that automated testing has tripped over the user of the -msb1-pass1-workarounds option, rather than fixing it remove support for pass 1 parts. Probably nobody will notice. I seem to own the last know pass 1 board and I haven't noticed another one in the wild in the past decade, at least. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
