ARM: dts: msm: Fix BT current leakage in msmcobalt MTP and CDP

Browse source 
There is a current leakage on S5 and LDO XO RF rail during
BT sleep. To prevent the current leakage, L7A/L17A/L25A
should be on during BT sleep. So, change L7A/L17A/L25A LDOs
from pin control version to SW control not to follow HW_EN2.
RFCLK2 has not been turned off during sleep and caused
extra current penalty. For RFCLK2 to follow HW_EN2 pin control,
clk_rf_clk2_pin should be used.
