Move the Data Pins to a new Symbol

Here we will edit the SDL to move the Data Pins to a new Symbol

First we rename the ALL_SIGNAL_PINS symbol placeholder to ADDRESS_CTL_PINS

Its as easy as inserting an End of Symbol marker before the BALANCE_SYM_SIDES directive we had used to separate the data from the Address

and then Adding a new start of symbol in place of the BALANCE_SYM_SIDES directive.

Then we change the New SYMBOL NAME placeholder to DRAM_DATA_PINS.

By default, the Symbol Name placeholder gets added just below the bottom of its symbol, So its good to enter a descriptive name
