Subject: [PATCH v1 21/50] ARM: dts: exynos: add OPP into FSYS APB bus in
 Exynos5420

Add an OPP for FSYS APB which reflects the real possible frequency.
The bus will have a new parent clock which speed has 600MHz, thus
a new possible frequency provided by the clock divider is 150MHz.
According to the documentation max possible frequency for this bus is
200MHz.
