arm: K3: Increase default SYSFW image size allocation

The memory allocated to store the FIT image containing SYSFW and board
configuration data is statically defined to the largest size expected.
Some additions to the board configuration data has pushed us slightly
over the current defined size on some HS devices, expand to 278000.
