Removed newline between the comment block and function definition
It enables vscode intellisense to display documentation about functions

Now that all families have support for calculating the clock of the
uart, use that layer. Slightly slower for "old" families, but the only
way to be correct for newer families.

Required so that the common uart infrastructure can be updated. This was
the last family to receive this implementation.

Follow HACKING specifications, be consistent with all other parts.
Yes, the SEL suffix is kinda superfluous, but it's _consistent_ which is
why we do it.

Cleanup one function at a time. Use the correct doxygen references, use
unshifted forms in user facing apis. Yes, only the trigger at the
moment, as the polarity is shared.

Add definitions for all the specific options, as is done for other
families.

(Added extra g0 definitions that were missed)
CCR register definitions were completely wrong, both decimal/hex mixups,
and straightup transcriptions from the reference manual errors.
Unify the styles for both g0 and g4, using the same (duplicated)
function for both implmentations.

Adds handling for missing cases. While i2c only has 3 cases, uarts have
all 4, so make sure they're handled properly.
Removes duplicated/redundant definitions.
Adds doxygen wrappers, even if only for internal use.

It's simply a wrapper around rcc_reset_pulse already.
Just drop it. See 034dbf20ff for the same deletion for timers.

A bunch of periphs on newer parts weren't defined. Add their
enable/reset bit definitions so they can be used.

Breaking: renames some irqs to be more specific and better match with
refman. We're still in the "between" tags, so break all the toys!

Avoid use of the gnu specific "asm" keyword, and use the __asm__
keyword, as used everywhere else in the library. This fixes compilation
in C11, and unifies all uses of asm literals in the codebase.

- rcc_get_i2c_clk_freq: Add support by taking RCC_CCIPR2 into account for I2C4.
- rcc_get_timer_clk_freq: Add support for LP timers
- rcc_get_usart_clk_freq: Fix APB freq used for LPUART1 and UART1, respectively.
This commit adds support for NRF52 TWI Master mode and slightly extends
existing I2C API. This is a breaking change, while mode selection needs to be
done during enabling I2C. There is one additional breaking change done because:
1) Unicore MX API design was PITA for writes
2) It is incompatible with EasyDMA
I strongly apologize to all two users who might be affected by this change.
