video: ipu reg: Correct reserved array size in struct ipu_idmac

The array reserved as a placeholder in the structure ipu_idmac
should contain 44 32bit unsigned integer entries instead of 45
ones, because the placeholder is located bewteen the register
IDMAC_SC_CORD1 and the register IDMAC_CH_BUSY_1 with the address
offsets of 0x804c and 0x8100 respectively.
