5e2600eb3a imx233: make microphone bias, bias pin and resistor configurable
This clearly fixes recording on targets where the bias pin was wrong. It may
also improve recording on targets where the bias voltage was wrong. I was unable
to find those parameters on the ZEN Mozaic, which fallback to default values.

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
