[PATCH 16/16] soc: imx: gpcv2: remove waiting handshake in power up

[Peng Fan (OSS)]

From: Peng Fan <peng.fan at nxp.com>

i.MX8MM has blk ctl module, the handshake can only finish after setting
blk ctl. The blk ctl driver will set the bus clk bit and the handshake
will finish there. we just add a delay and suppose the handshake will
finish after that.
