ixl: fix big-endian hardware interface handlingHEADmain

Correct the byte order at the driver interfaces that do not operate in
host order. Encode little-endian Admin Queue VSI and MAC/VLAN fields,
and decode firmware-provided queue handles, statistics indices, and
event parameters before using them.

Decode transmit descriptor writeback before examining it, and construct
VLAN descriptor fields in host order for the final descriptor
conversion. Store paged HMC descriptors in little-endian form and retain
the selected field bits when reading HMC contexts.

Keep MMIO values in host order for bus-space accessors and remove the
obsolete le16_to_cpu no-op macro. In particular, retain the atomic
bus_space_read_8() used for 64-bit registers.

On big-endian systems, the unconverted perfect-match filter flag is
presented to firmware as 0x0100 instead of 0x0001. Firmware rejects that
command with EINVAL, leaving receive traffic functional only in
promiscuous mode.
