About set boot_on for clk32kg regulator

Hi Kevin,

For panda and blaze, wl12xx sdio card can't be found without set on label in struct omap4_clk32kg_idata, and after search maillist I found Vishal had posted patch for it.

But after more investigations, if clk32kg regulator isn't on then sdio bus can't probe wl12xx sdio card, which means it isn't possible to enable regulator in wl12xx driver. so I set boot_on as true for 32KG regulator as for power reason as follows. Is it reasonable or not? or is there other solution can fix this issue? thanks.
