Exynos5420: Fix up the i2c driver for use with the TPM driver

The TPM driver expects to call i2c_read with zero address length. The i2c
    driver wasn't prepared to handle that particularly in the case of reads
    because it expected to send an address before switching over to read mode for
    the data. This change also fixes up the read and write calls to consistently
    be read32 and write32 instead of readl and writel.
