[PATCH] arm64: dts: rockchip: fix eMMC reset polarity on PP-1516

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at cherry.de>

According to the Jedec 5.1 specification, the device is held in reset
when RST_n is low, therefore the polarity of the line must be that, as
specified in the Device Tree binding (mmc/mmc-pwrseq-emmc.yaml).

Due to the wrong polarity, eMMC devices with RST_n_FUNCTION[162]
bitfield [1:0] set to 0x1 (the default is 0x0) will be held in reset
forever.

PP-1516 is affected by the same issue that Cobra has and for which a
patch[1] has already been sent.
