98e2a3e429 Some fixes to the startup code - clocks configs (#89) 
* Reverted 1MHz clock generator to GCLK5 instead GCLK7
Fixed the clock divider of 1MHz clock generator to be 48 (its source is DFLL which clocking at 48MHz, so 48 / 48 = 1, it was 48 / 24 = 2).
Updated the PLLs to the proper Ratio afetr the change of the 1MHz clock source.
Disabled GCLK_GENCTRL_DIVSEL reg on the 12MHz clock generator, since this caused the clock to be 1.5MHz.

* Fixed a description comment.

d2620a72d2 Fix analog ref enums. (#83) 
AR_INTERNAL was removed in #74. Because of this, non-SAMD51 boards fail because AR_INTERNAL isn't defined.
This also define AR_INTERNAL_2V23, which is also used for non-SAMD51
boards.

2ca67fc36b Fix delayMicroseconds() on SAMD51 (#77) 
* Fix pulseIn() on SAMD51 by writing it in plain C, so that
the CM0+-specific pulse_asm won't need to be linked.
The SAMD51 is fast enough that we can time pulses with micros()
Tested with a bunch of pulse lengths from <1us to >1s

* Implement a new delayMicroseconds() function for SAMD51
This version enables the "Debug Watchpoint and Trace" module (DWT)
in startup.c and then uses the 32bit cycle counter that is part
of DWT to count cycles indepenent of instruction timing.
Tested for good accuracy with various values between 1 and 2000us.

2bb54068a2 Don't reallocate USB buffers if already allocated 
USB Configuration was meant to run only once, but if the board comes back from standby the host can reconfigure the device again.
Probably a cleaner patch could be free()-ing the buffers on standby() to release the memory but at least we don't leak anymore.

9a49ce2fc4 Improve interrupt handling response time 
Change the way ISRs are stored. Store now in a list on a ‘first come
first served basis’, the first interrupt that gets attached will be
served first. This improves the speed of the ISR calling from about 6us
to 2us for a single interrupt on extint14

b627e00b17 Add USB send timeout 
Timeout is checked on the next send attempt. Initial timeout is set to
70ms, after a time out occurs and the previous transfer is still not
complete a send will report as failed. If a send times out, a ZLP will
be in the send queue to check for future timeouts.

a9127228d6 USB: Slightly refactored EP OUT handler 
Now the release() function only performs the action that is called for,
i.e. release the endpoint and let it receive data. All the buffers handling
has been inlined in the callers, this also slightly improves performance
because it allows to remove some redundant checks.
