Subject: [PATCH v2 3/3] ARM: EXYNOS: Remove left over 'extra_save'

Since 32b0aa9aaeb4 ("ARM: EXYNOS: Remove i2c sys configuration related
code") the Exynos 5250 no longer saves additional registers under
'exynos_pm_data.extra_save' field.

No one else uses this code so get rid of it making also 'exynos_pm_data'
const everywhere.

Signed-off-by: Krzysztof Kozlowski <k.kozlowski@...sung.com>
