It's now using completely the same driver as Sansa daps.
This also increases the volume range.

This port is a hybrid native/RaaA port. It runs on a embedded linux system,
but is the only application. It therefore can implement lots of stuff that
native targets also implement, while leveraging the underlying linux kernel.
The port is quite advanced. User interface, audio playback, plugins work
mostly fine. Missing is e.g. power mangement and USB (see SamsungYPR0 wiki page).
Included in utils/ypr0tools are scripts and programs required to generate
a patched firmware. The patched firmware has the rootfs modified to load
Rockbox. It includes a early/safe USB mode.
This port needs a new toolchain, one that includes glibc headers and libraries.
rockboxdev.sh can generate it, but e.g. codesourcey and distro packages may
also work.
Most of the initial effort is done by Lorenzo Miori and others (on ABI),
including reverse engineering and patching of the original firmware,
initial drivers, and more. Big thanks to you.

- enhance registers description in header file with respect to the as3543
registers: point which one are present or not in the as3543, which bits
change (i didn't detail all registers)
- cache less registers, only up to the ones which are written to
multiple times
- use ascodec_readbytes() to cache all needed registers in a row
- separate the as3543 bits from as3514/as3515 in audiohw_preinit()
- comment out unused audiohw_set_lineout_vol
- some cosmetics

- 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.

-> Change references to as3517 into as3515
there is a reference to the as3515 in the public as3525 datasheet to
support this fact
as3517 is used in the as3527 SoC, the (public) as3527 datasheet has
detailed information on its registers
the audio codec/PMU used in as3525v2 (thought to be as3543) appears to be
compatible (identical?) with as3517

If the bit 6 is set volume is much lower, without writing it explicitely
it is undefined.
According to linux sources this bit is related to mixer.
Initialize Audioset2 with low power 'hph' (probably headphones) quality,
as I couldn't make a difference with 'high quality' setting.

Add HAVE_AS3543 config define to differentiate the bits changed since as3514/as3517
Enable recording on Fuzev2/Clipv2/Clip+, although it was tested on Clip+ only
Note: storage is still read-only so I tested by listening to headphones loopback and watching the recording level in recscreen

Implement the missing API (ascodec_readbytes, ascodec_(un)lock)
