Platform: Clean up uart_stdout
Details:
- Change the functions used to redirect standard output to UART not to
be declared as weak symbol. These symbols are declared as weak in the
standard library. They are intended to be "overridden" by the
application. And the application in this case is TF-M.
- Remove uart_putc from uart_stdout.h because it should only be used
from uart_stdout.c. All writes to UART should happen through library
functions that are writing to standard out.
- Remove uart_getc as it is not used.
- Add comments
- Fix coding style issues
