Krzysztof Kozlowski 56a7c53c49 soc: samsung: exynos-asv: handle reading revision register error 
commit 4561560dfb4f847a0b327d48bdd1f45bf1b6261f upstream.

If regmap_read() fails, the product_id local variable will contain
random value from the stack.  Do not try to parse such value and fail
the ASV driver probe.
