In SMP mode, if all cores start at same time, all from __start(),
then only primary need do initialize, so others core should wait
primary, use 'sev' let the non-primary continue to __cpuN_start().

The IDMA needs to have 32 bit word alignment, in fact it will
AND off the lower 2 bits of the value stored in IDMABASE0R.
This bug was masked by CONFIG_ARMV7M_DCACHE causing proper word alignment
and also FAT_DMAMEMORY being aligned.
This commit extends the unaligned logic (used for dcache) to take into account
the need for a buffer copy when the buffer is ot 32 bit word.
It leverages the fact that when CONFIG_ARMV7M_DCACHE is not defined the up_xxxxx_dcache are nops.

Config option IMXRT_ADCx_ETC can now be used to select an external HW
trigger to be used instead of continous trigger. Continous trigger is
used if IMXRT_ADCx_ETC = -1 (default option). Otherwise the source signal
is routed through XBAR and used as a trigger.
Hardware triggering is currently limited to maximum of 8 channels.
HW trigger is automatically disabled if there are more than 8 channels.
The external triggering was tested with PWM signal as a source.

This commit supplements commit 7d877fbb. External sync mode is now
disabled if XBAR connection fails and config options are used directly
in sync_src variable and passed to XBAR macro only when needed. The first
option could caused an undefined behaviour when sync_src was equal to -1
(external sync not used)

1. remove task0 form runninglist
2. take task1 as new tcb
3. add task0 to blocklist
4. clear spinlock
4.1 remove task2 form runninglist
4.2 take task0 as new tcb
4.3 add task2 to blocklist
