Antonio Borneo f5657aa76e tcl: [1/3] prepare for jimtcl 0.81 'expr' syntax change
Jimtcl commit 1843b79a03dd ("expr: TIP 526, only support a single
arg") drops the support for multi-argument syntax for the TCL
command 'expr'.

In the TCL scripts distributed with OpenOCD there are 1700+ lines
that should be modified before switching to jimtcl 0.81.

Apply the script below on every script in tcl folder. It fixes
more than 92% of the lines
