[PATCH] revert ath5k ioread32()/iowrite32() usage - use readl()/writel(), we're MMIO-only

["Luis R. Rodriguez" <mcgrof@xxxxxxxxx>]

Based on advise from Jeff, as described in the e-mail:

[PATCH] Clarify pci_iomap() usage for MMIO-only devices

we shouldn't use ioread32()/iowrite32() unless we really have a need
to otherwise we're creating an unnecessary branch on read/write. Lets
revert this back to readl()/writel() as our devices so far have been
MMIO-only. This reverts 9202ec15da36ca060722c363575e0e390d85fb71 on
ath5k. This patch is intended for the ath5k branch of wireless-dev.
