Input: ims-pcu - fix DMA mapping violation in line setup
In ims_pcu_line_setup(), the driver uses pcu->cmd_buf as a transfer
buffer for usb_control_msg(). However, pcu->cmd_buf is embedded in the
struct ims_pcu allocation, which violates DMA mapping rules regarding
cacheline alignment.
Use a heap-allocated buffer for the line coding data instead.
