Input: i8042 - fix Pegatron C15B ID entry

The Zenbook Flip entry that was added overwrites a previous one
because of a typo:

In file included from drivers/input/serio/i8042.h:23,
                 from drivers/input/serio/i8042.c:131:
drivers/input/serio/i8042-x86ia64io.h:591:28: error: initialized field overwritten [-Werror=override-init]
  591 |                 .matches = {
      |                            ^
drivers/input/serio/i8042-x86ia64io.h:591:28: note: (near initialization for 'i8042_dmi_noselftest_table[0].matches')

Add the missing separator between the two.
