arm64: dts: rockchip: Enable HS400 for Indiedroid Nova

Once the DLL_STRBIN_TAPNUM_DEFAULT is set to the correct value [1], the
workaround to ensure stable eMMC operation is no longer needed. I
have observed testing this that hdparm went from:
"Timing buffered disk reads: 502 MB in  3.00 seconds = 167.14 MB/sec"
to the following:
"Timing buffered disk reads: 832 MB in  3.00 seconds = 277.32 MB/sec"
