drm/panel: novatek-nt35560: avoid on-stack device structure

[ Upstream commit 1a7a7b80a22448dff55e1ad69a4681fd8b760b85 ]

A cleanup patch apparently by accident used a local device structure
instead of a pointer to one in the nt35560_read_id() function, causing
a warning about stack usage:

drivers/gpu/drm/panel/panel-novatek-nt35560.c: In function 'nt35560_read_id':
drivers/gpu/drm/panel/panel-novatek-nt35560.c:249:1: error: the frame size of 1296 bytes is larger than 1280 bytes [-Werror=frame-larger-than=]

Change this to a pointer as was liley intended here.
