This patch expands the voltage range of buck1/3 regulator due to as following:
- MIF (Memory Interface) bus frequency needs the 9uV ~ 105uV V.
- INT (Internal) bus frequency needs 9uV ~ 100uV.

THis patch adds the bus device tree nodes for both MIF (Memory) and INT
(Internal) block to enable the bus frequency.
The DMC bus is parent device in MIF block using VDD_MIF and the LEFTBUS
bus is parent device in INT block using VDD_INT.
