643c0a1e0e imx233: simplify timrot API
The old timrot setup API was very low-level and unfriendly. The new one
makes in easier to select the frequency source. Use to simplify timer
and kernel timer code.

eac1ca22bd imx233: generate register headers using headergen_v2 and update code for it
NOTE: this commit does not introduce any change, ideally even the binary should
be almost the same. I checked the disassembly by hand and there are only a few
differences here and there, mostly the compiler decides to compile very close
expressions slightly differently. I tried to run the new code on several targets
to make sure and saw no difference.

The major syntax changes of the new headers are as follows:
- BF_{WR,SET,CLR} are now superpowerful and allows to set several fileds at once:
  BF_WR(reg, field1(value1), field2(value2), ...)
- BF_CS (use like BF_WR) does a write to reg_CLR and then reg_SET instead of RMW
- there is no more need for macros like BF_{WR_,SET,CLR}_V, since one can simply
  BF_WR with field_V(name)
- the old BF_SETV macro has no trivial equivalent and is replaced with its
  its equivalent for BF_WR(reg_SET, ...)

I also rename the register headers: "regs/regs-x.h" -> "regs/x.h" to avoid the
redundant "regs".

Final note: the registers were generated using the following command:
./headergen_v2 -g imx -o ../../firmware/target/arm/imx233/regs/ desc/regs-stmp3{600,700,780}.xml

34fb6906dd imx233: preventive fix of timrot
The old could trigger an immediate IRQ if for example the count was 0
when setting up the timer: since the count was updared *after* clearing the
IRQ, it could fire in between.

This should hopefully fix some audio glitches

f5ac658d16 imx233: normalise clkctrl
The clkctrl functions were becoming a mess. Normalise the names,
get rid of the xtal derived as special case and use the same
interface.

9ced006c06 imx233: move icoll stuff to its own file
The icoll code now has an IRQ storm detection mechanism which
will prevent the device from hard freezing in case it happen.
