'char const' means the same thing as 'const char', but we
use the former in only a handful of places and we use the
latter over six thousand times. Switch the imx reg_name()
functions to bring them in line with everything else.

Move the inclusion out of hw/hw.h, most files do not need it.

EPIT, GPT and other i.MX timers are using "abstract" clocks among which
a CLK_IPG_HIGH clock.

On i.MX25 and i.MX31 CLK_IPG and CLK_IPG_HIGH are mapped to the same clock
but on other SOC like i.MX6 they are mapped to distinct clocks.

This patch add the CLK_IPG_HIGH to prepare for SOC where these 2 clocks are
different.

Most clocks supported by the CCM are useless to the qemu framework.

Only clocks related to timers (EPIT, GPT, PWM, WATCHDOG, ...) are usefull
to QEMU code.

Therefore this patch removes clock computation handling for all clocks but:
* CLK_NONE,
* CLK_IPG,
* CLK_32k

This way all CCM clock defines/enums are named CLK_XXX

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

Replace the uint32 softfloat-specific typedef with uint32_t.
This change was made with

find include hw fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\buint32\b/uint32_t/g'

together with manual removal of the typedef definition,
manual undoing of various mis-hits, and another couple of
fixes found via test compilation.

All the uses in hw/ were using the wrong type by mistake.
