The existing bridge command is incomplete and it has spelling error. This newly
added help text indicates the bit positions and the values of the mask.
ie: bit 0 = h2f/s2f, bit 1 = lwhps2fpga, and bit 2 = f2h/f2s

These bridges available only in Stratix 10:
bit3: f2sdram0
bit4: f2sdram1
bit5: f2sdram2
