af47faf650 kmp204x: complete the reset sequence and PRST configuration
This adds the reset support for the following devices that was until
then not implemented:
- BFTIC4
- QSFPs

This also fixes the configuration of the prst behaviour for the other
resets: Only the u-boot and kernel relevant subsystems are taken out of
reset (pcie, ZL30158, and front eth phy).

Most of the prst config move to misc_init_f(), except for the PCIe
related ones that are in pci_init_board and the bftic and ZL30158 ones
that should be done as soon as possible.

Only the behavior of the Hooper reset is changed according to the
documentation as the application is not able to not configure the switch
when it is not reset.

a53e65d053 kmp204x: Add support for the unit LEDs
The unit LEDs are managed by the QRIO CPLD. This patch adds support for
accessing these LEDs in the QRIO.

The LEDs then are set to a correct boot state:
- UNIT-LED is red
- BOOT-LED is on.

87ea2c0ff3 kmp204x: introduce QRIO GPIO functions
The QRIO GPIO functions can be of general interest. They are thus added
to a qrio.c and their prototype are available from kmp204x.h. The QRIO
prst function are also included in this file, as well as the functions
required for the I2C deblocking support (open-drain).
