[ARM] 4081/1: Add definition for TI Sync Serial Protocol

Of the possible SSP frame formats (FRF bits in SSCR0), only SSCR0_PSP is defined. Other possible formats are Motorola SPI (0<<4), TI SSP (1<<4) and Microwire (2<<4). Attached patch adds a definition SSCR0_TISSP.
This mode is used for the sound codec attached to the PXA272 SSP1 of some HTC PDA phones.
