r2d: Fix flash memory size, sector size, width, device ID
pflash_cfi02_register() takes a size in bytes, a block size in bytes and a number of blocks. r2d_init() passes FLASH_SIZE, 16 * KiB, FLASH_SIZE >> 16. Does not compute: size doesn't match block size * number of blocks. The latter happens to win: FLASH_SIZE / 4, i.e. 8MiB. The best information we have on the physical hardware lists a Cypress S29PL127J60TFI130 128MiBit NOR flash addressable in words of 16 bits, in sectors of 4 and 32 Kibiwords. We don't model multiple sector sizes. Fix the flash size from 8 to 16MiB, and adjust the sector size from 16 to 64KiB. Fix the width from 4 to 2. While there, supply the real device IDs 0x0001, 0x227e, 0x2220, 0x2200 instead of zeros.
