Introduce a new .init section for initialisation code, so that it can be copied to an area which is later overwritten before calling. The stack/bss can then overwrite that code, effectively freeing the code size that the initialisation routines need. Gives a few kB ram usage back.
Only implemented for PP and as3525 so far. More targets could be added, as well as more functions.

- cache IRAM and DRAM
- map IRAM just next to DRAM to remove the need for -mlong-calls and reduce binsize
- tweak delays in Fuze button code
- tweak delays in Clip button code (down button sometimes doesn't respond anyway : an alternate driver is being worked on)

Activates IRAM for AMS Sansas to be used by codecs and core. Fixes Reboot-on-mp3 and gives speed up on codecs using IRAM in general.
I've made a change: the core/codec ratio is 0x20000/0x30000 instead of 0x10000/0x40000, 0x30000 is way more than codecs currently use (0x14000 at max) and the core might need more than 0x10000.

Note that on low memory targets (Clip/m200v4 tested) you will encounter
random crashes. Applying FS#9332 seems to help a lot.

Adds read-only SD driver, largely copied from ata-sd-pp.c
Only tested on the embedded SD, on the Clip
