Sean Cross f002c784c0 nrf: linker: add a new .uninitialized section
This section immediately follows the .bss section, and is designed to
contain uninitialized variables that should persist across reboots.

The section is placed directly after .bss, under the theory that the
size of Circuit Python's .bss + .data is bigger than the bootloader's
.bss + .data, so there is less likely to be a conflict.

This adds preliminary support for the nRF52833, which is a variant of

Add PacketBuffer and MTU negotiation support.
PacketBuffer facilitates packet oriented BLE protocols such as BLE
MIDI and the Apple Media Service.

This also adds PHY, MTU and connection event extension negotiation
to speed up data transfer when possible.
