i2c: pxa: use official address byte helper
i2c-pxa was created before i2c_8bit_addr_from_msg() was implemented, and used its own i2c_pxa_addr_byte() which is functionally the same. Sadly, it was never updated to use this new helper. Switch it over. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: Wolfram Sang <wsa@kernel.org>
