Remove old config file for SENTRY5

This is an older broadcom part that implements the mips32 ISA. 32-bit
FreeBSD/mips now requires mips32r2, so retire this config. Most of the
broadcom port is shared with newer ports, so what little code may be
unique to this part has not been GC'd at this time.

-# The Broadcom Sentry5 series of processors and boards is very commonly
-# used in COTS hardware including the Netgear WGT634U.
-#
-# Some tweaks are needed for use with this platform:
-#
-# * CFE firmware's ELF loader expects an ELF kernel which is linked so as
-#   not to contain offsets in PT_LOAD which point behind the actual offset
-#   of that PT header. FreeBSD normally links the first PT_LOAD header to
-#   begin at offset 0.
-#
-# * Broadcom's support package for the internal bus, the Sonics
-#   SiliconBackplane, needs to be integrated to detect and probe hardware
-#   correctly.
-#
-# * The clock needs to be calibrated correctly, so that DELAY() may work.
-#   One problem with this is that the low-level printf() routine calls DELAY(),
-#   which currently causes divide-by-zero trap
-#
-# * The Broadcom CPUs have no FPU. Attempting to detect one by reading CP1's
-#   status register causes an unhandled boot-time exception. An FPU emulator
-#   will be necessary to support multi-user boot.
