Here is a collection of fixes/small additions to Odroid-C4 & Odroid-HC4 concerning
regulators handling, USB and SPI NOR Flash of HC4.
Changes from v1 at [1]:
- added review tags from martin
- removed invalid patch about hub_5v
- added proper vcc_5v gpio control
- removed invalid hub_5v regulator already controlled by a gpio hog

As described in the schematics of Odroid-C4 and Odroid-HC4, the TF_IO regulator
is enabled by the GPIOE_2 GPIO and gets it's supply from VCC_5V.

According to Odroid-C4 & HC4 Schematics, the TF_3V3N_1V8_EN can be in Hi-Z for 3v3,
and since it's the default GPIOAO_6 mode at reset, let switch this GPIO as Open-Source
to drive for 1, and input for 0.

As described in the Odroid-C4 & Odroid-HC4 schematics, the 5V regulator is controlled
by GPIOH_8 and in Open Drain since this GPIO doesn't support Push-Pull.

As described in the HC4 schematics, only the USB port B is used,
port A is left unconnected. Thus disable PHY0 and remove it from PHYs list.

As described in the HC4 schematics, GPIOH_8 controls the USB 5V and 12V
regulators used to power the SATA drives.
And is set as Open Drain since this GPIO doesn't support Push-Pull.

Drop the hub_5v regulator which controls the HUB Reset line with GPIOH_4 which
is already controlled by a GPIO HOG.
Until we can properly describe how to control USB HUBs reset lines, keeping
the GPIO HOG is an acceptable solution we use on multiple boards.

Drop the hub_5v regulator which controls the HUB Reset line with GPIOH_4 which
is already controlled by a GPIO HOG.
Until we can properly describe how to control USB HUBs reset lines, keeping
the GPIO HOG is an acceptable solution we use on multiple boards.
