util/intelp2m: Update output information format in the comments

Update the information format in the comments above the macros in the
generated gpio.h file:

PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_39, UP_20K, DEEP, NF1, TxLASTRxE,
DISPUPD), /* LPSS_UART0_TXD */ -->(i)

/* GPIO_39 - LPSS_UART0_TXD */ --> (ii)
/* DW0: 0x44000400, DW1: 0x00003100 */ --> (ii)
/* DW0 : PAD_TRIG(OFF) - IGNORED */ --> (iii)
PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_39, UP_20K, DEEP, NF1, TxLASTRxE,
DISPUPD),

Also, in the case of field macros, the utility with -iiii generates an
additional comment that contains the target PAD_CFG() macro:

/* PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_39, UP_20K, DEEP, NF1, TxLASTRxE,
DISPUPD), */ --> (iiii)

TEST:
git clone https://github.com/maxpoliak/inteltool-examples.git test
./intelp2m -n -file test/inteltool-asrock-h110m-stx.log
./intelp2m -fld cb -file test/inteltool-asrock-h110m-stx.log
./intelp2m -fld fsp -file test/inteltool-asrock-h110m-stx.log
./intelp2m -fld raw -file test/inteltool-asrock-h110m-stx.log

Before and after (now with -i key) the patch, gpio.h is no different.
