[PATCH 1/2] ARM: PRIMA2: add of_dev_auxdata table for I2C, SPI, UART and PINCTRL

[Barry Song]

From: Barry Song <Baohua.Song at csr.com>

This patch adds lookup table for attaching a specific name and platform_data
pointer to devices like i2c, spi, uart and pinctrl as they get created by
of_platform_populate().  Ideally this table would not exist.
