NR UE: fix PRACH generation with frequency resource id not 0 when msg1-FDM > 1 in SIB1

When msg1-FDM > 1 (2, 4 or 8) in SIB1, the frequency resource id of
PRACH could be not 0, current PRACH generation only considers frequency
resource id = 0. This MR fixes it, verified with 3rd-party gNB.

Closes #939
