msm: mdss: Unlock correct mutex in AD setup

The incorrect mutex for the BL file descriptor was being unlocked

unlock on the correct mutex.

msm: mdss: Separate AD info from AD hardware base address

Splitting the AD info struct, which is used primarily to store state, from
the hardware blocks. Functionality is preserved by passing the structures
containing hardware information to the functions that execute the register
writes. This change is necessary for dual pipe operation where one AD state
machine controls more than one AD hardware block.

ARM: Don't dump vmalloc addresses with show_data()

Memory-mapped IO address spaces cannot be safely dumped at will.
Some addresses may not be available (clocked, powered) at all times,
and may result in hangs or bus decode errors if accessed. Other
registers that are accessible may have read side-effects, and dumping
them may have adverse affects on stability or the functionality of
the affected peripheral.

Be safe, and skip dumping such addresses altogether.

ARM: Improve vmalloc address checking in show_data()

There is an unhandled corner case with the current check
which has recently been hit. The nbytes argument may be
large enough for the range being dumped to cross a
boundary between page-table mappings, and dump addresses
which are vmalloc'd in the neighboring mapping.

Check every address being dumped to see if its vmalloc'd,
not just the address passed to show_data().

MDP clocks were not voted for while AD stabilization was in progress,

Make sure MDP clocks are voted for as long as AD is stabilizing.
