i2c: pxa: move private definitions to i2c-pxa.c
Move driver-private definitions out of the i2c-pxa.h platform data header file into the driver itself. Nothing outside of the driver makes use of these constants. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: Wolfram Sang <wsa@kernel.org>
