i2c: exynos5: Preserve high speed master code
When the driver starts to send a message with the MASTER_ID field
set (high speed), the whole I2C_ADDR register is overwritten including
MASTER_ID as the SLV_ADDR_MAS field is set.
This patch preserves already written fields in I2C_ADDR when writing
SLV_ADDR_MAS.
Fixes: 8a73cd4cfa15 ("i2c: exynos5: add High Speed I2C controller driver")
