Uart example

[huntc]

Provides the simplest example of using UART for both the 52840 and 9160.

Tested successfully on:

• nrf52840-dk
• nrf9160-dk
• Thingy:91 (having modified the GPIO pins locally)

@jonathanpallant Can you elaborate further on the changes re 1ba3630 and why they are necessary? I was expecting to implement the nrfx workaround when initialising the UART for the 53 and 91 boards (see description), not a change for all boards. Thanks.

I've just seen #319. I shall revert your commit here @jonathanpallant and turn this PR into simply providing an example of using UART for nrf-hal. Thanks.

[huntc]

@jonathanpallant Reverted your commit given the UART improvements/fixes elsewhere and made this just an example of how to set the UART up.

No more changes expected here. Please review/merge accordingly.

I think we should remove embed.toml, and add 9160 to the xtask list, but otherwise looks OK.

I provided the embed.toml to be consistent with the other examples. Could we look at the example deployment strategy as a separate issue to this PR? All but one of the examples has an embed.toml.

I will do this shortly. Thanks.

[huntc]

The 9160 for the hello world example is now included in the xtask.

Oh! I totally didn't spot they'd been added to all the other examples. Yes, of course, we should be consistent.
