ARM: dts: qcom: Update USB settings for L1 LPM on Lahaina 

The USB controller supports link power management (L1 LPM) for
high speed. Remove the "snps,dis_enblslpm_quirk" property which
disables that feature. While there, clean up the "snps,hird-threshold"
value as that is only supposed to be 4-bits; the 5th bit is set by a
separate property "snps,is-utmi-l1-suspend". These will allow for
maximum power savings when connected in USB 2.0 mode and L1 LPM
is supported for both host and peripheral modes.

Finally, remove the unused "usb-core-id" properties.
