BIOS does configured the SerDes. The problem here is that all the
configurations done by BIOS are being reset at xpcs_create().

We would want user of the pcs-xpcs module (stmmac, sja1105) to have
control whether or not we need to perform to the soft reset in the
xpcs_create() call.
I understood Andrew's response as suggesting to introduce the ability for
xpcs_create() to make a BIOS call which would configure the SerDes after
xpcs_soft_reset().
Yes. Exactly. That is what ACPI is for, so we should use it for this.
