Felipe Balbi a390e85cfe wl12xx: move common init code from bus modules to main
Move all common parts from sdio.c and spi.c to main.c, since they now
can be handled as part of the platform driver.

[forward-ported, cleaned-up and rephrased commit message]
[added a bunch of fixes and a new pdata element]
