Interrupts version is cause of freeze on USB extraction.
Also non-interrupts version much simpler and faster.

It was possible for interrupts of higher priority than the current IRQ
level to attempt to restart the interface while it was still active on
a transfer. The list modification also wasn't protected within the I2C
ISR itself.

move prototypes to ascodec.h
move code to ascodec*.c
YPR0: use adc-as3514.c instead of duplicating it
TODO: merge as3514.h and ascodec.h ?

We need it for correct charger detection if we boot with charger plugged
because there is no edge interrupt

reorder static functions to avoid the need for early prototypes
panic if the INT_AUDIO callback could not read the 3 IRQ_ENRD registers

- Enable end of charge monitoring once, it doesn't need to be disabled
- Acknowledge the first (wrong) end of charge interrupt on charger enable
(this had been broken in r25299)
- Centralize reads to ENRD* registers and cache the results when needed
- on PP it is not needed because reads are atomic, we only check for
end of charge when the charging, and for charger presence when
discharging
as3525v2 (using as3543) specifics
- I got the datasheet today from AMS, thanks to them for being so fast
and not require me to sign tons of papers!
- USB detection now works on as3525v2 using the as3543. Clip+ won't
reboot to OF yet, it needs mkamsboot support first (usbstack disabled)
- Charging should work, the CHARGER register is at a different place, it
is an extended PMU register -> use ascodec_read/write_charger() to
access it
- real interrupts are not used yet for ENRD, we get thousands of
interrupts per second, apparently only limited by the i2c clock.

i2c clock frequency uses pclk as reference, not plla
i2c clock divider is only 10 bits, not 16
