MIPS: BCM1480: remove checks for CONFIG_SIBYTE_BCM1480_PROF

There are two checks for CONFIG_SIBYTE_BCM1480_PROF in the tree since v2.6.15. The related Kconfig symbol has never been added to the tree. So these checks have always evaluated to false. Besides, one of these checks guards a call of sbprof_cpu_intr(). But that function is not defined. Remove all this.

Untested.

Until v2.6.23 there also were checks for CONFIG_SIBYTE_SB1250_PROF in the tree. There also was a Kconfig symbol SIBYTE_SB1250_PROF so it was possible to make these checks evaluate to true. But, since one of these checks also guarded a call of sbprof_cpu_intr(), that should have made the build fail with an error.

The Sibyte profiling was far inferior to later solutions such as oprofile or perf and non-standard anyway. So let's kill what's left over.
