Anton Vorontsov b3319b1052 fsl_pq_mdio: Fix iomem unmapping for non-eTSEC2.0 controllers 
We use a rather complicated logic to support eTSEC and eTSEC2.0
registers maps in a single driver. Currently, the code tries to
unmap 'regs', but for non-eTSEC2.0 controllers 'regs' doesn't
point to a mapping start, and this might cause badness on probe
failure or module removal:

 Freescale PowerQUICC MII Bus: probed
 Trying to vfree() nonexistent vm area (e107f000)
 ------------[ cut here ]------------
 Badness at c00a7754 [verbose debug info unavailable]

 [...]

 LR [c00a7754] __vunmap+0xec/0xf4
 Call Trace:

Fix this by introducing a proper priv structure (finally!), which
now holds 'regs' and 'map' fields separately.
