ARM: dts: s5pv210: align pin configuration nodes with bindings

Bindings expect that pins in initial and sleep states nodes end with
'-pin':

  s5pv210-fascinate4g.dtb: pinctrl@e0200000: sleep-state: 'gpa0-0', ...
    'mp07-7' do not match any of the regexes: '^(pin-[a-z0-9-]+|[a-z0-9-]+-pin)$', 'pinctrl-[0-9]+'
