ASoC: Davinci: Replace usage of IO_ADDRESS with ioremap()
This patch modifies the Davinci i2s and mcasp drivers to make use of ioremap() instead of IO_ADDRESS() Signed-off-by: Vaibhav Bedia <vaibhav.bedia@ti.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
