arm64: dts: exynos5433: specify the SPI FIFO depth

Up to now the SPI alias was used as an index into an array defined in
the SPI driver to determine the SPI FIFO depthj Drop the dependency on
the SPI alias and specify the SPI FIFO depth directly into the SPI node.

The FIFO depth were determined based on the SPI aliases that are defined
in exynos5433-tm2-common.dtsi:
spi0 = &spi_0;
spi1 = &spi_1;
spi2 = &spi_2;
spi3 = &spi_3;
spi4 = &spi_4;
spi-s3c64xx.c driver defines the following fifo_lvl_mask for the
"samsung,exynos5433-spi" compatible:
.fifo_lvl_mask = { 0x1ff, 0x7f, 0x7f, 0x7f, 0x7f, 0x1ff},
Thus spi{0, 4} were considered having 256 byte FIFO depths, and
spi{1, 2, 3} having 64 byte FIFO depths. Update device tree with these
FIFO depths. No functional change expected.

arm64: dts: exynos5433: add specific compatibles to several blocks

Exynos5433 reuses several devices from older designs, thus historically
we kept the old (block's) compatible only. This works fine and there is
no bug here, however guidelines expressed in
Documentation/devicetree/bindings/writing-bindings.rst state that:
1. Compatibles should be specific.
2. We should add new compatibles in case of bugs or features.

Add compatibles specific to Exynos5433 in front of all old-SoC-like
compatibles. This will also help reviews of new code using existing
DTS as template. No functional impact on Linux drivers behavior.

arm64: dts: exynos: Fix wrong label for USB 3.0 controller node

Exynos5433 has two usb 3.0 controllers: usbhost and usbdrd. usbhost
is host-only controller whereas usbdrd supports both peripheral and
host mode. "drd" means dual-role device, so usbhost cannot be labeled
with the name containing "drd". However, the label usbdrd_dwc3_0 was
used for usbhost's dwc3 node. It seems it obviously fault because TM2
and TM2E doesn't use usbhost but dr_mode property is assigned to it.

This patch assigns the proper label for two dwc3 nodes.
