MIPS: Get rid of 'kgdb_early_setup' cruft.
Commit 854700115ecf ([MIPS] kgdb: add arch support for the kernel's kgdb core)
added the 'kgdb_early_setup' flag to avoid calling trap_init() and init_IRQ()
the second time, however the code that called these functions earlier, from
kgdb_arch_init(), had been already removed by that time, so the flag never
served any useful purpose. Remove the related code along with ugly #ifdef'ery
at last.
[ralf@linux-mips.org: Folded in Guenter Roeck's fix.]
