HID: sony: Use kernel allocated buffers for HID reports

Replace stack buffers with kernel allocated buffers for sending
and receiving HID reports to prevent issues with DMA transfers
on certain hardware.

Output report buffers are allocated at initialization time to avoid
excessive calls to kmalloc and kfree.
