[PATCH 4/4] arm64: dts: Add ARM PL022 SPI DT nodes for NS2

[Anup Patel]

We have two ARM PL022 SPI instances in NS2 SoC. On NS2 SVK,
one of the ARM PL022 SPI host has Silabs si3226x slic connected
to chip-select #0 whereas second ARM PL022 SPI host has Atmel
AT25 EEPROM connected to chip-select #0.

This patch adds ARM PL022, Silabs si3226x, and Atmel AT25
DT nodes in NS2 DT and NS2 SVK DT respectively.
