Make the entry of Dalmore Power Management Unit device TPS65913
in dalmore DTS file. The Palma driver support this device.

Enable following submodule of the TPS65913:
- GPIO driver
- RTC driver.
- Power regulator driver.

Changes from V1:
- renames nodes from palams_* to simple as gpio, rtc, pmic etc.
- Added line gap properly.
- Remove comment for palams-gpio reference as the entry itself explain.
- Remove unit address for tps65913.

Changes from V2:
- Made LDO9 as always ON for sd card functionality.

Hi Stephen,
I observed that if sd card is not initailised in bootloader then it will not get
enumerated in the kernel also. In my case, I am using fastboot and hence it is 
not
observed that sd card is getting initialised.
But today I use the uboot and on this, sd card is getting enumerated. And 
observer that
LDO9 is getting disabled in late init call due to full constraint and it can 
create
issue for sd card. With this modified patch I make the LDO9 as always ON.

I am not able to validate this througly as the kernel crash in the method of 
uboot. Need
more debugging.
