MIPS: powertv: Drop BOOTLOADER_DRIVER Kconfig symbol

The kbldr.h header file required for this was neither committed in the
original submission in a3a0f8c8
"MIPS: PowerTV: Base files for Cisco PowerTV platform"
nor was it ever present in the git tree so this option never worked.
Fixes the following build problem:
arch/mips/powertv/reset.c:25:36: fatal error: asm/mach-powertv/kbldr.h: No such
file or directory
compilation terminated.
