rsdproto board support has wrong I2C frequency and wrong return value
handling.

Ugh.  I *hate* to back this change out, but these compiler flags don't
work for relocation on all versions of GCC.  I've not been able to
reproduce the environment in my setup (and hence, not been able to
find a combination that *does* work), so I've got no choice but to go
back to the old gcc flags and linker script.

Although mips_io_port_base is currently a part of IDE command, it is quite
fundamental for MIPS I/O port access such as in[bwl] and out[bwl]. So move
it to MIPS general part, and introduce `set_io_port_base()' from Linux.

This patch is triggered by multiple definition of `mips_io_port_base' build
error on gth2 (and tb0229 also needs this fix.)

Spartan2/3 FPGAs. The old code used "< 0" on a "char" type to test if
the most significant bit was set, which did not work on any
architecture where "char" defaulted to be an unsigned type.

Sometimes you can't reference the DDR2 controller variables.
