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.

-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.
