stm32/mpconfigport.h: Use IRQ_PRI_PENDSV to protect bluetooth ringbuf.

Browse Source 
The default protection for the BLE ringbuf is to use
MICROPY_BEGIN_ATOMIC_SECTION, which disables all interrupts. On stm32 it
only needs to disable the lowest priority IRQ, pendsv, because that's the
IRQ level at which the BLE stack is driven.
