There are currently no nodes that use spi0 so remove the enabled
property for it in the beaglev ahead and lpi4a dts files. It can be
re-enabled in the future if any peripherals will use it. The definition
of spi0 remains in the th1520.dtsi file.

Adjust labels for the TH1520 GPIO controllers such that GPIOs can be
referenced by the names used by the documentation. Eg.
GPIO0_X -> <&gpio0 X Y>
GPIO1_X -> <&gpio1 X Y>
GPIO2_X -> <&gpio2 X Y>
GPIO3_X -> <&gpio3 X Y>
GPIO4_X -> <&gpio4 X Y>
AOGPIO_X -> <&aogpio X Y>
Remove labels for the parent GPIO devices that shouldn't need to be
referenced.

created spi0 node with fixed clock. the spi0 node
uses synopsis designware driver and has the following
compatible "snps,dw-apb-ssi". the spi0 node is connected
to a SPI NOR flash pad which is left unpopulated on the back
side of the board.

The BeagleV Ahead single board computer uses the T-Head TH1520 SoC.
Add a minimal device tree to support basic uart/gpio/dmac drivers so
that a user can boot to a basic shell.
