qca-ssdk: disable building ISISC

ISISC is the QCA codename for their Atheros switch family including
AR237, QCA8337 etc.

Since we have qca8k support in OpenWrt, there is no need to have SSDK
support for these switches, and boards that also have external switches
can just use qca8k.

Disable QCA803x PHY support as well, since all of those are supportable
via at803x driver.
