Rework for AGL UCB integration
Changes include: - The provided kernel patches have been reworked to not modify the salvator-x(s) devicetree source, but to introduce new files for the reference hardware instead. There is some possibility that the reference hardware devicetree could be based off the the salvator-x with some work and perhaps splitting of the salvator-x source, but for now the aim is to avoid breaking the salvator-x(s) with the reference hardware changes. - The modifications to the r8a7795 pinctrl driver have been replaced with a splitting of the USB interface OVC pins into their own pin groups, which has previously been done for other older Renesas hardware. This allows booting the reference hardware off of the same kernel as other H3 boards, at the expense of minor devicetree modifications for them (e.g. h3ulcb). There is likely some more work required if this needs to be upstreamed, as the ulcb.dtsi changes would mean that the pinctrl drivers for M3 would also need the new pin groups. - All changes for the ST asm330lhh driver addtion have been moved to that patch to the kernel. - A machine conf file has been added for "agl-refhw-h3", and the firmware documentation updated to document how to set up a build of the firmware using it. This is required due to the firmware options from this layer's arm-trusted-firmware bbappend not being compatible with other H3 boards (eMMC versus Hyperflash boot). A definition of the COMPATIBLE_MACHINE variable has been added to that bbappend to make sure that attempting to use it with another H3 machine will trigger an error. In AGL, the bbappend will need to be masked out with BBMASK for now. - The top-level README file has been updated to reflect the expected integration in AGL.
