    soc: renesas: renesas-soc: Release 'chipid' from ioremap()
    
    [ Upstream commit fc187a46a8e682f0f1167b230792b88de01ceaa0 ]
    
    Smatch reports:
    
    drivers/soc/renesas/renesas-soc.c:536 renesas_soc_init() warn:
    'chipid' from ioremap() not released on lines: 475.
    
    If soc_dev_atrr allocation is failed, function renesas_soc_init()
    will return without releasing 'chipid' from ioremap().
    
    Fix this by adding function iounmap().
