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.
* added: Linker script adds support for RAM4 and RAM5 memory regions, so
that those are usable by code. This also fixes the fact that RAM4 was
declared, but inaccessible previously
* changed: RAM1 is renamed to RAM2, shifting numbering of all regions.
This is done in order to be in line with other STM32 definitions,
similarly ROM1 became ROM2.
by making it vaguer. These days, there's extra timers that support the
BDTR register, so the simple "advanced" timer description is no longer
sufficiently clear. You have to check your particular reference manual.

Presumably copy/paste error in original submission.
Verified in RM0440rev1 and rev5.

* merged: nrf tree from unicore-mx
* fixed: small changes to make merged code play with rest of locm3 again
* added: linker script generator defines for nRF51/52 stubs
* added: doxygen support
This removes code and changes names and styles where relevant to be more
inline with normal libopencm3.
NRF52x library is built for hardfloat, M4F by default. The M4 no float
variants are less common, and if needed, the library can be built
manually for those variants. Unless some very common boards show up
using those parts, we don't need an extra library build.
