TomoYamanaka b528fbdfb3 Implementation of USTICKER feature for Renesas mbed boards
I implemented USTICKER feature.

The mainly changing is here.
- I added a macro to mbed_drv_cfg.h for commonalizing code for GR-PEACH and GR-LYCHEE with different clock frequencies, and referenced it's macro at us_ticker.c.
- ticker_init()
  Currently, ticker_init() keep counting, disables the ticker interrupt, and is safe to call repeatedly.
  Therefore, in order to satisfy specifications, I removed GIC_EnableIRQ at end of function and added GIC_DisableIRQ at begin of function.
  When an interrupt is required, it will be set with ticker_set_interrupt().
  If executing the following, the counter has been initialized. So it will not call after executing the first time.
    OSTM1TT   = 0x01;    /* Stop the counter and clears the OSTM1TE bit.     */
    OSTM1TS   = 0x1;    /* Start the counter and sets the OSTM0TE bit.     */

- ticker_free()
  this function stops the counting and powerdown the us_ticker.
  To satisfy the mbed specificationm, I implemented free() function.

- ticker_read()
  Currently, Mbed spec's frequeny is between 250KHz and 8MHz, but the frequency that is used at my ticker is 33MHz.
  Therefore, in order to satisfy specifications, I changed the process to return the timer counter value divided by 32(33MHz / 32).
  Since the calcurate function by using 64 bit is no longer necessay, I removed it.

- ticker_set_interrupt()
  Same as the above read(),
  In order to satisfy specifications, I changed the process to set the value multiplied by 32.

- ticker_fire_interrupt()
  In order to satisfy specifications, I implemented fire_interrupt() function.
  Also I added GIC_EnableIRQ for allowing the interrupt at end of function.

- ticker_get_info()
  To satisfy the mbed specificationm, I implemented ticker_get_info() function. The value of freq includes rounding off.

TomoYamanaka 8b7e2abdb7 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
