Commits 1019fe2c7280 ("ARM: dts: exynos: Adjust bus related OPPs to the
values correct for Exynos5422 Odroids") and 9ff416cf45a0 ("ARM: dts:
exynos: Disable frequency scaling for FSYS bus on Odroid XU3 family")
revealed that 'opp-shared' property for the Exynos bus OPPs was used
incorrectly, what had the side-effect of disabling frequency scaling for
the second and latter buses sharing given OPP-table.
Fix this by removing bogus 'opp-shared' properties from Exynos3 bus
OPP-tables. This restores frequency scaling for the following busses:
RightBus, LCD0, FSYS and MFC.
