pmdomain: core: Reduce debug summary table width

commit c6ccb691d484544636bc4a097574c5c135ccccda upstream.

Commit 9094e53ff5c86ebe ("pmdomain: core: Use dev_name() instead of
kobject_get_path() in debugfs") severely shortened the names of devices
in a PM Domain.  Now the most common format[1] consists of a 32-bit
unit-address (8 characters), followed by a dot and a node name (20
characters for "air-pollution-sensor" and "interrupt-controller", which
are the longest generic node names documented in the Devicetree
Specification), for a typical maximum of 29 characters.

This offers a good opportunity to reduce the table width of the debug
summary:
  - Reduce the device name field width from 50 to 30 characters, which
    matches the PM Domain name width,
  - Reduce the large inter-column space between the "performance" and
    "managed by" columns.

Visual impact:
  - The "performance" column now starts at a position that is a
    multiple of 16, just like the "status" and "children" columns,
  - All of the "/device", "runtime status", and "managed by" columns are
    now indented 4 characters more than the columns right above them,
  - Everything fits in (one less than) 80 characters again ;-)

[1] Note that some device names (e.g. TI AM335x interconnect target
    modules) do not follow this convention, and may be much longer, but
    these didn't fit in the old 50-character column width either.
