bcm53xx: drop unneeded 4.3 SPROM patch

4.3 isn't oficially used anymore but it may be useful for debugging PCI
host driver regression. SPROM driver doesn't seem to work correctly with
4.3:
[    2.336686] bcma: bus0: Using fallback SPROM failed (err -2)
[    2.342366] bcma: bus0: No SPROM available
but it at least compiles now.

-Subject: [PATCH 03/17] bcm47xx-sprom: add Broadcom sprom parser driver
-
-This driver needs an nvram driver and fetches the sprom values from the
-nvram and provides it to any other driver. The calibration data for the
-wifi chip the mac address and some more board description data is
-stores in the sprom.
-
-This is based on a copy of arch/mips/bcm47xx/sprom.c and my plan is to
-make the bcm47xx MIPS SoCs also use this driver some time later.
