This adds supoprt for the Atmel SAMD51 & SAME54 SoC.
The SAME5x/SAMD5x is a line of Cortex-M4F MCUs that share peripherals
with the samd2x Cortex-M0+ and saml1x Cortex-M23 parts.
Atmel Software Framework (ASF) provides a set of low-level header files
that give access to different hardware peripherals of Atmel's ICs.

This cleans up the sam0 timer driver:
- remove the check for the unused freq parameter
- the MCU provides dedicated SET/CLR registers to avoid
read-modify-write, so don't do read-modify-write on them.
- workaround a possible hardware bug on SAMD5x:
loop until the CMD_READSYNC is really set
The existing periph_uart test depends on having more than one UART.
This test allows for manual testing with the use of a probe

This change required correcting the values for LCRH_PEN and LRCH_EPS
values defined in cc26x0_uart.h, as they were incorrect according to
19.8.1.7 of the TI CC26x0 reference manual.

`tsrb` changed to that type, so there is no reason for us, to keep the
internally used buffer as a `char` (especially since the rest of the
driver already uses `uint8_t`)
The API of `tsrb` was changed because of confusing type situations.
This API change takes this API change of changing `char` to `uint8_t`
up a level. Since `isrpipe` most often is used together with
`periph_uart` this change even is beneficial, as `periph_uart` also
uses `uint8_t` instead of `char`.
Having the input type `char` makes the output of `tsrb_get_one()`
incomparable to the input of `tsrb_add_one()`. By changing it to
`uint8_t` we not only definitively fix it to an octet, but also ensure
that the input and output are the same.
