[PATCH AUTOSEL 5.10 03/17] soc: mediatek: Let PMIC Wrapper and SCPSYS depend on OF

[ Upstream commit 2778caedb5667239823a29148dfc48b26a8b3c2a ]

With the following configuration options:
CONFIG_OF is not set
CONFIG_MTK_PMIC_WRAP=y
CONFIG_MTK_SCPSYS=y
we get the following build warnings:

  CC      drivers/soc/mediatek/mtk-pmic-wrap.o
drivers/soc/mediatek/mtk-pmic-wrap.c:2138:34: warning: ‘of_pwrap_match_tbl’ defined but not used [-Wunused-const-variable=]
drivers/soc/mediatek/mtk-pmic-wrap.c:1953:34: warning: ‘of_slave_match_tbl’ defined but not used [-Wunused-const-variable=]
  CC      drivers/soc/mediatek/mtk-scpsys.o
drivers/soc/mediatek/mtk-scpsys.c:1084:34: warning: ‘of_scpsys_match_tbl’ defined but not used [-Wunused-const-variable=]

Looking at the code, both drivers can only bind to OF-defined device
nodes, so these drivers are useless without OF and should therefore
depend on it.

Also drop of_match_ptr() from both drivers. We already know what it
will resolve to, so we might as well save cpp some work.

Developers or QA teams who wish to test-build the code can still do
so by enabling CONFIG_OF, which is available on all architectures and
has no dependencies.
