bcm27xx: remove no-op patch pair 

Patch 1 introduces a change, and patch 2 reverts it again. Remove
both patches and achieve the same outcome.

Refreshed patches for the target as well.

Subject: [PATCH] staging: vchiq_arm: Fix platform device
unregistration
In error case platform_device_register_data would return an ERR_PTR
instead of NULL. So we better check this before unregistration.
Fixes: 37b7b3087a2f ("staging/vc04_services: Register a platform device for the camera driver.")

Subject: [PATCH] staging: vchiq_arm: Unify the unload handling of
platform devs
A helper function vchiq_register_child was added to deal with
adding the platform devices. This returns NULL on failure, and
that is assigned to the struct platform_device. There is
therefore no way for remove to encounter an error pointer, so
checking for IS_ERR() is redundant.
