So far, only hard power off could reset GPIOs state to defaults:
IN, Open-drain. Now, defaults are set with every boot to ensure
that GPIOs are not in unknown/unwanted state.

* Add function to generate unique _UID using CRC32
* Add function to write the _UID based on a device's ACPI path
ACPI devices that have the same _HID must use different _UID.
Linux doesn't care about _UID if it's not used.
Windows 10 verifies the ACPI code on boot and BSODs if two devices
with the same _HID share the same _UID.
Fixes BSOD seen on Windows 10.

Some mainboards with an ASPEED BMC do the serial routing setup in the
BMC boot phase on cold boot. This results in scrambled console output
when this is not finished fast enough.
This adds a delay of 500ms as workaround in the BMCs uart setup that
can be selected at mainboard level.
A user may disable the workaround when using another BMC firmware like
OpenBMC, u-bmc or some custom BMC bootloader with fast serial setup.
