linux-wandboard: Remove usused patch and INC_PR

The kernel is based on Freescale 3.0.35-4.0.0 kernel and has the
4.6.9p11 Vivante GPU code applied so the patch is unused but was
leftover.

The INC_PR were not being used so this has been dropped as well.

        into Freescale's 3.0.35 kernel but is definitely present in 3.0.35):
ebad167 boundary defconfigs: add Device Mapper for use with Debian installer
9a25a36 Revert "nitrogen6x: add OSS audio"

The INC_PR set has been removed as it were not being used in the
recipe and we don't need to change PR anymore, in usual cases.
