[PATCH 2/2] drivers/usb/typec/tps6598x.c: fix 4CC cmd write

[Nikolaus Voss]

Writing 4CC commands with tps6598x_write_4cc() already has
a pointer arg, don't reference it when using as arg to
tps6598x_block_write(). Correcting this enforces the constness
of the pointer to propagate to tps6598x_block_write(), so add
the const qualifier there to avoid the warning.

Fixes: 0a4c005bd171 ("usb: typec: driver for TI TPS6598x USB Power Delivery controllers")
