The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have
been kept around for migration reasons.  After more than two years it's
time to remove them finally.

This patch cleans up one of the remaining users.  When all such patches
hit mainline we can remove the defines and typedefs finally.

Impact: cleanup

Convert the last remaining users and remove the typedef.

Impact: Fix section mismatch.

clocks_init() has been called from twl4030_probe() which is a non-init
function. Since probing can be done anytime so clocks_init will be
called anytime too. So we mark clock_init() as non-init.

WARNING: drivers/mfd/built-in.o(.text+0x8dd9): Section mismatch in
reference from the function twl4030_probe() to the function

The function twl4030_probe() references
the function __init clocks_init().
This is often because twl4030_probe lacks a __init
annotation or the annotation of clocks_init is wrong.

In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

Due to the way that the WM8350 audio driver handles CODEC_ENA many of
the WM8350 audio registers are marked as volatile when they aren't
actually so. Allow the audio driver to see a cache of these values for
inspection during interrupt context.

To do this we need to stop satisfying any bits from volatile registers
from cache - there's no real benefit from doing so anyway, we did the
read already.

Some I2C controllers have high overheads for setting up I2C operations
which makes the register cache setup on startup excessively slow since
it does a lot of small transactions. Reduce this overhead by doing a
bulk read of the entire register bank and filtering out what we don't
need later.
