board: 8226: add AUXDATA for SMSC HUB device

AUXDATA should be passed to update HSIC device name. This
is required for getting clock resources and userspace apps
that uses device name for proper functioning. In case of
HSIC connection using SMSC HUB, HSIC host is added as a
child node of SMSC HUB. Hence, pass auxdata for SMSC_HUB
which points to the child node's (HSIC_HOST) auxdata.
