RCC_HCLK_DIV1 translates to 0x0 while apb_psc uses the value defined
by CONFIG_CLOCK_STM32_APB1/2_PRESCALER (range from 1 to 16).
Manually check if the defined prescaler is 1 or not and use that to
calculate the correct timer clock.

Default configuration for USART1 (Console output) on board
stm32f3_disco was set on PA9/PA10, which matches Rev-A/B
configuration. Though, on more recent configuration of the
board (Rev-C onward). USART1 is mapped to PC4/PC5.
This configuration has the benefit to support VCP, hence it
is chosen to be set by default.

TEMT is Transmitter Empty bit which is set only when the full FIFO
is empty. It makes sense to poll for THRE (Transmitter Holding
Register Empty) which is set when UART can buffer new character
for transmission (there is room in FIFO). This allows using the
FIFO in full.

Add flash page layout support for STM32F4 SoCs.
This almost eliminates the need for flash_map.h, except for
STM32F4X_SECTOR_MASK, so delete the file and move the define into the
F4 implementation, to keep things simple.

This is a prep work commit for adding flash page layout support.
The internal flash APIs for STM32 on L4 and F4 are a bit
inconsistent. Some routines take a pointer to the private data, others
don't. Those that do take it as a last argument instead of a
first. Additionally, some APIs are declared in flash_stm32.h that
aren't ever used by the family-specific files.
Clean this up by making everything take a struct device*, and marking
routines static in the common driver code when possible.

Added an internal function to obtain the flash page layout in
run-length encoded format. The API is simple and allows the actual
public API implementations to be simple and maintainable.
This feature can be enabled by using the FLASH_PAGE_LAYOUT Kconfig
option. This API is required for the implementation of flash file
system.
Added a public API to get flash page information (size and start offset)
by offset within the flash and by index of the page.
Added a generic implementation of the internal flash_get_page_info API.
Added an additional public API call to get the total count of pages in
the flash memory and its generic implementation.

nrf SOC uses nrf rtc timer (not sys tick), which is 32kHz,
whereas CPU runs at higher speed (nrf52 runs at 64MHz).
So 32Khz is too slow to measure critical kernel parameters.
This patch does :-
1. Add support for nrf SOC for timing_info benchmarking.
2. Uses SOC timer to measure kernel parameters.

1. changing API/Variable names to generic one.
2. Creating some of Macros whose implimentation is platform
depenent.
