usb: host: tegra: Resetting PORT0 based on information received via DT.
Tegra USB host driver is using port instance number, to handle some of the hardware issues on SOC e.g. reset PORT0 twice etc. As instance number based handling looks ugly, making use of information passed through DT for achieving this.

/*
 * Register a set of sysctl names by calling register_sysctl_table
 * with an initialised array of struct ctl_table's.  An entry with 
 * NULL procname terminates the table.  table->de will be
 * set up by the registration and need not be initialised in advance.
 *
 * sysctl names can be mirrored automatically under /proc/sys.  The
 * procname supplied controls /proc naming.
 *
 * The table's mode will be honoured both for sys_sysctl(2) and
 * proc-fs access.
 *
 * Leaf nodes in the sysctl tree will be represented by a single file
 * under /proc; non-leaf nodes will be represented by directories.  A
 * null procname disables /proc mirroring at this node.
 *
 * sysctl(2) can automatically manage read and write requests through
 * the sysctl table.  The data and maxlen fields of the ctl_table
 * struct enable minimal validation of the values being written to be
 * performed, and the mode field allows minimal authentication.
