As the timer 2 is on APB1 bus, the maximum of clock frequency of APB1 timer
clock is half of SYSCLK. Then to calculate the timer prescaler for timer 2
which need to be divided by 2.

This configuration should be valid for all F7 family devices in general.
Here is the regions info:
- Region0 : 4GB : cacheable & executable.
- Region1 : 512MB : text area : strogly ordered & executable.
- Region2 : 512MB : peripherals : device memory & non-executable.
- Region3 : 512MB : peripherals : device memory & non-executable.
- Region4 : 512MB : cortexM area: strongly ordered & non-executable.
Higher region number overrides the lower region configuration.

Use the clock setup function defined in clock.c instead of setting the
clock bits directly in the drivers.
Remove register definitions of RCC in rcc.h as these are already
defined in the struct in stm32.h

Per Vikas' request, the problem this commit is supposed to be solving is
something he doesn't see and further this introduces additional hardware
requirements.

This change is to remove a halt at about 200KiB
while sending a large(1MiB) binary to a micro controller using USART1.
USART1 is connected to a PC via an on-board ST-Link debugger
that also functions as a USB-Serial converter.
However, it seems to loss some data occasionally.
So I changed the serial port to USART6 and connected it to the PC using
an FTDI USB-Serial cable, therefore the transmission was successfully
completed.
