samd21/gpio: check if interrupt is enabled in isr, fixes #4087
...
The interrupt flag for a previously configured external gpio interrupt
will be set regardless of the actual configuration. So when another source
causes an interrupt, the callback of a disabled gpio interrupt will be serviced
although it was disabled if the interrupt occured in the meantime.

cpu: removed NAKED attribute from ISRs
...
- removed the __attribute__((naked)) from ISRs
- removed ISR_ENTER() and ISR_EXIT() macros
Rationale: Cortex-Mx MCUs save registers R0-R4 automatically
on calling ISRs. The naked attribute tells the compiler not
to save any other registers. This is fine, as long as the
code in the ISR is not nested. If nested, it will use also
R4 and R5, which will then lead to currupted registers on
exit of the ISR. Removing the naked will fix this.
