Michal Lenc 69249fc9e6 drivers/ioexpander/iso1i813t.c: fix error startup condition 
The reference manual (section 3.2.1) states the user has to
read GLERR and INTERR registers to clear their bits and release
ERR pin after the startup sequence. Error bits are set to 1 after
the startup if external power supply is used.

Not clearing the bits leads to subsequent read call errors if VBB
errors are checked.
