Commonalize the files in "targets/TARGET_RENESAS/TARGET_RZ_A1XX" directory

I made be available in common whatever the board related to RZ_A1 in the below files.
- Since there are the table code of Pinmap differs for each board, I moved the code to "PeripheralPins" file for each board, and changed to include PeripheralPins.h.
  analogin_api.c, can_api.c, gpio_irq_api.c, i2c_api.c, pinmap.c, port_api.c, pwmout_api.c, serial_api.c, spi_api.c and us_ticker.c

- Since there are some board-specific processes, I enclosed the processes with "#ifdef" and rearranged the functions to make be easier to enclose.
  can_api.c, ethernet_api.c and serial_api.c

- Since there are the driver configuration values differs for each board, I added "mbed_drv_cfg.h" file for each board and defined macros for the values, and changed to refer to the macros.
  can_api.c, gpio_api.c, pwmout_api.c and rtc_api.c
