arm64: dts: hisilicon: hikey960: Drop "snps,gctl-reset-quirk" and "snps,tx_de_emphasis*" properties

"snps,tx_de_emphasis" is supposed to be a u8, not a u32. Since it is big
endian, 0 will be read rather than 1. The DWC3 Linux driver simply ORs
the value if "snps,tx_de_emphasis_quirk" is set, so the 2 properties
have no effect. (The driver doesn't clear the field either which is
another problem).

"snps,gctl-reset-quirk" is not documented nor used in the driver, so
drop it as well.
