Subject: thermal: armada: Update Armada 380 thermal sensor coefficients

From: Nadav Haklai <nadavh@marvell.com>

commit efa86858e1d8970411a140fa1e0c4dd18a8f2a89 upstream.

Improve the Armada 380 thermal sensor accuracy by using updated formula.
The updated formula is:
Temperature[C degrees] = 0.4761 * tsen_vsen_out - 279.1
