Now that we got a PCS driver, use it and remove the now redundant
PCS code and it's header macros from the Ethernet driver.

The Wireless Ethernet Dispatch subsystem on the MT7622 SoC can be
configured to intercept and handle access to the DMA queues and
PCIe interrupts for a MT7615/MT7915 wireless card.
It can manage the internal WDMA (Wireless DMA) controller, which allows
ethernet packets to be passed from the packet switch engine (PSE) to the
wireless card, bypassing the CPU entirely.
This can be used to implement hardware flow offloading from ethernet to
WLAN.

The driver depends on mmio regmap API but doesn't select the appropriate
Kconfig option. This fixes it.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

This patch adds support for the MediaTek MT7628/88 SoCs to the common
MediaTek ethernet driver. Some minor changes are needed for this and
a bigger change, as the MT7628 does not support QDMA (only PDMA).

The Mediatek MT7621 SoC contains the same ethernet hardware module as
used on a number of other MediaTek SoC parts. There are some minor
differences to deal with but we can use the same driver to support
them all.
This patch is based on work by Bjørn Mork <bjorn@mork.no>, and his
original patch is at:
https://github.com/bmork/LEDE/commit/3293bc63f5461ca1eb0bbc4ed90145335e7e3404
There is an additional compatible devicetree type added, and the primary
change to the code required is to support a single interrupt (for both
RX and TX interrupts).

This patch is the preparation patch in order to adapt into various
hardware through adding platform data which holds specific characteristics
among MediaTek SoCs and introducing the unified clock handler for those
distinct clock requirements depending on different features such as
TRGMII and SGMII getting support on the target SoC. And finally, add
enhancement with given the generic description for Kconfig and remove the
unnecessary machine type dependency in Makefile.
