We can call commands like dhcp and bootp without arguments or with
explicit command line arguments that really should tell the code where
to look for files instead.

Unfortunately, the current code simply overwrites command line arguments
in the dhcp case with dhcp values.

This patch allows the code to preserve the command line values if they
were set on the command line. That way the semantics are slightly more
intuitive.

The reason this patch does that by introducing a new variable is that we
can not rely on net_boot_file_name[0] being unset, as today it's
completely legal to call "dhcp" and afterwards run "tftp" and expect the

Masking clock gate, reset register bits based on the
probed controller is proper only due to the assumption
that masking should start with 0 even thought the controller
has separate PHY or shared between OTG.

unfortunately these are fixed due to lack of separate
clock, reset drivers.

Say for example EHCI1 - EHCI3 in the datasheet (EHCI0 is for the OTG)
so we need to start reg_mask 0 - 2.

This patch calculated the mask, based on the register base
so that we can get the proper bits to set with respect to
probed controller.

We even do this masking by using PHY index specifier from dt,
but dev_read_addr_size is failing for 64-bit boards.
