I successfully identified the STC/RDS pin as B2P27.
Strangely the OF uses polling instead of interrupts
but since they routed it, let's use it! On the fuze+
the fmradio i2c uses bit toggling so we can't read
the RDS data in the interrupt context. Instead we
defer the work to a thread.

Past development has proved that one can mistakely use
the same pin for two uses without noticing. Since this
causes extremely hard to find bugs, the infrastructure
will allow to register pin uses and panic when a conflict
is detected. The pinctrl debug now shows the pin uses
when its support is compiled in.

It was only needed by the old arm toolchain that we no longer use or support.

Player-specific code remaining: usb_drv_(init,exit)
The iPods lack a MMU, so:
- physical, virtual, and uncached addresses are identical
- since we can't access uncached memory we discard caches when receiving data
Still not quite reliable on nano2g

- Add BUTTON_POWER.
- hm60x: Rename BUTTON_PLAY to more proper BUTTON_SELECT, which will make it
possible to unify hm60x and hm801 keymaps in some plugins.

Remove the implementations of all exceptions handlers from the
various crt0.S files and have a single implementation in system-arm.h
The new implementation is weak so that it can be overwritten by some
specific code (like the unwinder)

This patch implements HAVE_ADJUSTABLE_CPU_FREQ, it modifies the
following parameters when CPU is unboosted:
- s5l8702 voltage is decreased: 1.200V -> 1.050V
- CPU frequency is divided by 4: 216MHz -> 54MHz
- AHB frequency is divided by 2: 108MHz -> 54MHz

For now it contains explicit SDRAM setup, cutting clock for unused
modules and turning off unused PLLs. This improves slightly mem
throughput as well as saves quite a bit of power.

Rework code to be more useful:
- move battery channel init to lradc
- always init lradc from system (previously from adc)
- don't reserve channels for vddio, nmos or pmos
- implement external temperature sensing using current source
- use this for battery sensing on the Fuze+ (calibration needed)

Yeah, sizeof (void) here with GCC is 1. If something has a problem
with that, we'll set it straight.
