regulator: qcom_smd: fix overlooooong supply names

The regulator framwork limits the name of a regulator supply to 32
characters:
|static struct device_node *of_get_regulator(struct device *dev, const char *supply)
|{
|	struct device_node *regnode = NULL;
|	char prop_name[32]; /* 32 is max size of property name */
|
|	dev_dbg(dev, "Looking up %s-supply from device tree\n", supply);
|
|	snprintf(prop_name, 32, "%s-supply", supply);
|	regnode = of_parse_phandle(dev->of_node, prop_name, 0);

Thus, names like 'vdd_l8_l9_l10_l11_l12_l13_l14_l15_l16_l17_l18'
cannot be successfully looked up in DT. Use an abbreviated name.
