This patch set is to add DT support for mxc_gpio driver.
patch 1/4 and 2/4, a new dev_get_addr interface is abstracted to
improve driver who want to get device address.
patch 3/4, add a new bank_index entry in platdata to avoid `plat - mxc_plat`
pointer subtract usage.
patch 4/4, add compatible ids and implement bind function. Also commented
out U_BOOT_DEVICES and mxc_plat, since they are not needed
if using DT.
Changes v3:
1. split bank_index patch
2. abstract dev_get_addr for driver
Changes v2:
1. remove uneccessary #ifdef
2. add more stuff in commit log
3. include a new function mxc_get_gpio_addr to get register base.
This function is different for DT and not DT, by `#ifdef`.
If using one implementation for DT and not DT, final image will be big.
4. include a new entry in platdata, named bank_index. it can simplify DT
support. To no DT, bank_index is static initilized; to DT, bank_index
is get from device's req_seq.
