net: hisilicon: hns: Remove reset helpers

With hns_dsaf_roce_reset() removed in a previous patch, the two
helper member pointers, 'hns_dsaf_roce_srst',  and 'hns_dsaf_srst_chns'
are now unread.

Remove them, and the helper functions that they were initialised
to, that is hns_dsaf_srst_chns(), hns_dsaf_srst_chns_acpi(),
hns_dsaf_roce_srst() and hns_dsaf_roce_srst_acpi().
