fbdev: imxfb: warn about invalid left/right margin

Browse source

[ Upstream commit 4e47382fbc ]

Warn about invalid var->left_margin or var->right_margin. Their values
are read from the device tree.

We store var->left_margin-3 and var->right_margin-1 in register
fields. These fields should be >= 0.
