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().
Fixes: cb5508e47e60 ("soc: renesas: Add support for reading product revision for RZ/G2L family")
