arm64: dts: rockchip: fix emmc reset polarity on px30-cobra

Technically, the reset signal is active low - it's called RST_n after all.

But it is ignored completely unless RST_n_FUNCTION=1 (byte 162 in extcsd)
is set in the emmc. It is 0 per default.

For emmcs that have RST_n_FUNCTION=1 we failed like this:

	[    3.074480] mmc1: Failed to initialize a non-removable card

With this change they work normally.
