uboot-mediatek: update to 2021.04-rc3 with MediaTek's patches
MediaTek published their current U-Boot patchset on github:
https://github.com/mtk-openwrt/u-boot/commits/mtksoc

Import the platform patches from there (`00-mtk-*.patch`), arrange,
them nicely, drop no longer needed local patches and rebase on top of
U-Boot 2021.04-rc3.

Tested and works well on Linksys E8450 (snand-1ddr) as well as
Bananapi BPi-R64 (sdmmc-2ddr, emmc-2ddr).

Subject: [PATCH 05/21] pinctrl: mediatek: do not probe gpio driver if not
enabled
The mtk pinctrl driver is a combination driver with support for both
pinctrl and gpio. When this driver is used in SPL, gpio support may not be
enabled, and this will result in a compilation error.
To fix this, macros are added to make sure gpio related code will only be
compiled when gpio support is enabled.
