[ Upstream commit 3eef2f48ba0933ba995529f522554ad5c276c39b ]
FWSPIDQ2 and FWSPIDQ3 are not part of FWSPI18 interface so remove
FWQSPID group in pinctrl. These pins must be used with the FWSPI
pins that are dedicated for boot SPI interface which provides
same 3.3v logic level.

The default pinmux configuration for Y23 is to route a heartbeat to
drive a LED. Previous revisions of the AST2600 datasheet did not include

The AST2600 pinconf is a little different from previous generations of
ASPEED BMC SoCs in terms of architecture. The pull-down setting is
per-pin setting now, and drive-strength support 4 kind of value (e.g.
4ma, 8ma, 12ma, 16ma).

AST2600 has two USB ports, A, B:
Port A supports 4 distinct modes:
1. PCIe EHCI to Hub
2. Hub to PHY
3. BMC EHCI to PHY
4. PCIe EHCI to PHY
Port B support 3 modes:
1. USB1.1 HID controller
2. USB2.0 Device controller
3. BMC EHCI port2
Implement pinmux support by mapping each ports' functions onto a single
pin group for each port.

Early revisions of the AST2600 datasheet are conflicted about the state
of the LPC/eSPI strapping bit (SCU510[6]). Conversations with ASPEED
determined that the reference pinmux configuration tables were in error
and the SCU documentation contained the correct configuration. Update
the driver to reflect the state described in the SCU documentation.

The AST2600 pinmux is fairly similar to the previous generations of
ASPEED BMC SoCs in terms of architecture, though differ in some of the
design details. The complexity of the pin expressions is largely reduced
(e.g. there are no-longer signals with multiple expressions muxing them
to the associated pin), and there are now signals and buses with
multiple pin groups.
The driver implements pinmux support for all 244 GPIO-capable pins plus
a further four pins that are not GPIO capable but which expose multiple
signals. pinconf will be implemented in a follow-up patch.
The implementation has been smoke-tested under qemu, and run on hardware
by ASPEED.
