Clock the SAMD21 much faster so it can actually convert at its max 
sample rate of 350ksps.

Also added an error check of sample rate.

Speed up zero neopixel pulses. 
SK6812 on 5v is pickier than WS2812 on 5v.

Hopefully fixes #1083.

UART: Always allocate UART objects in the long-lived pool

b0e33f6a11 atmel-samd: UART: allocate rx buffer in long-lived region 
This is not strictly needed in order for #1056 to be resolved,
because the "make long-lived" machinery is unaware of this pointer.

However, as UARTs are assumed to be long-lived, this change is
beneficial because it moves the long-lived buffer into the upper
memory area with other long-lived objects, instead of remaining in
the low heap.

e1b4e9b7c7 UART: Always allocate UART objects in the long-lived pool 
Particularly when they have buffers that are written via IRQ or DMA,
UART objects do not relocate gracefully.  If such an object is
relocated to the long-lived pool after its original creation, the
IRQ or DMA will write to an unexpected location within the Python
heap, leading to a variety of symptoms.  The most frequent symptom
is inability to read from the UART.

Consider the particular case of atmel-samd: usart_uart_obj_t
contains a usart_async_descriptor contains a _usart_async_device.
In _sercom_init_irq_param the address of this contained
_usart_async_device is assigned to a global array
sercom_to_sercom_dev which is later used from the interrupt context
_sercom_usart_interrupt_handler to store the received data in the
right ring buffer.

When the UART object is relocated to the long-lived heap, there's no
mechanism to re-point these internal pointers, so instead take the
cowardly way and allocate the UART object as long-lived.

Happily, almost all UART objects are likely to be long-lived, so
this is unlikely to have a negative effect on memory usage or heap
fragmentation.

Closes: #1056
