Haotian Zhang 8cacdb0f0b clk: renesas: r9a06g032: Fix memory leak in error path 
[ Upstream commit f8def051bb ]

The current code uses of_iomap() to map registers but never calls
iounmap() on any error path after the mapping. This causes a memory
leak when probe fails after successful ioremap, for example when
of_clk_add_provider() or r9a06g032_add_clk_domain() fails.

Replace of_iomap() with devm_of_iomap() to automatically unmap the
region on probe failure. Update the error check accordingly to use
IS_ERR() and PTR_ERR() since devm_of_iomap() returns ERR_PTR on error.
