Current code doesn't really enable the usb clocks so if they're disabled
when booting linux, the kernel/machine will hang as soon as someone is trying
to read a usb register

This patch is fixing some issues :
- MXC_OTG_UCTRL_OPM_BIT is for USBCTRL register and not PHYCTRL register.
- the MXC_EHCI_WAKEUP_ENABLED check was only clearing the bits so never allows
to set them.

There is necessary to flush dcache and invalidate
icache for address where breakpoint (brki r16, 0x18)
was. The reason is that for some cases icache line
still keeps brki instruction and it is not updated
by origin instruction maintains by gdbserver.

The error message 'NMI watchdog failed to create perf event...'
does not make it clear that this is a fatal error for the
watchdog. It also currently prints the error value as a
pointer, rather than extracting the error code with PTR_ERR().
Fix that.
Add a note to the description of the 'nowatchdog' kernel
parameter to associate it with this message.

- much improved implementation due to clean codec hierarchy
- preparation for potential per-codec spinlock change
NOTE: additionally removes a chip->pcm[codec_type] NULL ptr check
(due to it requiring access to external chip struct),
however I believe this to be ok since this condition should not occur
and most drivers don't check against that either.

This implements 64 bit statistics support and fixes races when reading
counter values. The PHY counters can only be accessed 16 bits at a time,
so they are subject to carry races.
NB:
* TX/RX counters are maintained in software because the the hardware packet count
is only a 32 bit value.
* Error counters are really only 32 bit.
* Old 32 bit counter fields in dev->stats still used for some
software counters
