[U-Boot] [PATCH v3 1/9] net: tsec: Refactor the readout of the tbi-handle property

[Vladimir Oltean <olteanv@gmail.com>]

The point of this patch is to eliminate the use of the locally-defined
"reg" variable (which interferes with next patch) and simplify the
fallback to the default CONFIG_SYS_TBIPA_VALUE in case "tbi-handle" is
missing.
