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.
