We can't pop into pc on ARMv4t when using thumb: the T bit won't be
modified if we are returning to a thumb function
Code running on ARMv4t should use the new ldrpc / ldmpc macros instead
of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc}
No modification on pure ARM builds and ARMv5+
Note: USE_THUMB is currently never defined, no targets can currently be
built with -mthumb, see FS#6734

preventing the DMA callback to advance in the recording buffer is not
enough in pcm_rec_dma_get_peak_buffer()
we need to prevent it interrupting us while we are copying the left
channel data into the right channel

(forward port of r26481 + cosmetics)
This lead to freezes under various conditons (bug report: FS#11267)
Battery life is almost not (if at all) affected:
- between 4 and 8 minutes less runtime for fuzev1
- 9 minutes less runtime for c200v2 (2 minutes difference on a 2 hours run)
Additional verifications of the runtime (including on other models) wouldn't hurt

this removes workaround for spurious interrupts added in r26316
side effect: make keyclicks work correctly when used intensively (with
the scrollwheel for example), the clicks should be inserted fast enough
for the PCM fifo to not become empty.
PL190 can cause spurious interrupts if an interrupt is triggered by a
peripheral shortly before the interrupt for this peripheral is cleared
from VIC registers.
As an effect we should only write in VIC_INT_EN_CLEAR after having
disabled the source of the interrupt in the peripheral.

Waiting for TRAN state after the end of the transfer caused writing problems for some uSD cards. Removing this wait returns write functionality to those cards.

Even if we disable it in VIC_INT_EN_CLEAR, it still fires an interrupt
by running the default isr.
Locking requires disabling interrupts completely.
I'm not sure if DMAC is the only interrupt affected or if we can't rely
on VIC_INT_EN_CLEAR to mask interrupts.
If it's the latter, we will need to have special locking scheme for
INT_AUDIO.

- retry failed commands up to 6 times
- wait at most 5 seconds for the card to go to TRAN state
- wait for the card to be in TRAN state (i.e. not programming) before
disabling SD clocks (remove the workaround in sd_enable() )

(playback + database/pictureflow updating)
