[PATCHv2] dmaengine: bestcomm: make gen_bd init helpers static

[PATCHv2] dmaengine: bestcomm: make gen_bd init helpers static

[Rosen Penev]

bcom_gen_bd_rx_init() and bcom_gen_bd_tx_init() are only called from
the PSC wrapper functions in gen_bd.c, so make them static, drop
their now-unneeded exports, and remove the corresponding header
declarations.

These had use before commit 7d3ee229ea51
("powerpc: Drop MPC5200 LocalPlus bus FIFO driver")

 v2: mention driver removal that made them unused.
