While comparing the vendor dts with the one added in v5.11-rc1 I noticed
that the vendor dts specified 3.3 V which matches the SDIO specification.
So fix the sdio regulator to provide (up to) 3.3 V.

* [PATCH 2/2] arm64: dts: rockchip: Rely on SoC external pull up on pmic-int-l

According to the schematic there is an external pull up, so there is no
need to enable the internal one additionally. Using no pull up matches
the vendor device tree.
