i2c: mvtwsi: Eliminate twsi_control_flags
In a system where the initial u-boot location is genuinely NOR flash (as opposed to RAM or a cache-line setup by a pre-bootloader) writes to the data section are problematic. At best these writes have no effect, at worst they put the flash memory into a status mode which changes the executable code underneath us. Pass around a stack variable from the top of the twsi i2c driver to avoid writing to global data. Signed-off-by: Chris Packham <judge.packham@gmail.com>
