Subject: [PATCH 5/8] caif-hsi: HSI-Platform device register and unregisters
 itself

From: Daniel Martensson <daniel.martensson@...ricsson.com>

Platform device is no longer removed from caif_hsi at shutdown.
The HSI-platform device must do it's own registration and unregistration.

Signed-off-by: Sjur Brændeland <sjur.brandeland@...ricsson.com>
