qualcommbe: ipq9574: describe remaining uniphy resets

Each uniphy has, besides the XPCS reset, a system reset in the GCC and
a soft reset in the NSSCC. The vendor driver pulses both on every
interface mode change as part of the uniphy bring-up. Describe them,
and name the resets while at it, so the PCS driver can pick them up.
