ata: pata_rb532_cf: use devm_platform_ioremap_resource()

Browse source

Replace the open-coded platform_get_resource() plus devm_ioremap()
sequence with a single devm_platform_ioremap_resource() call, which folds
the resource lookup and mapping into one step and returns an ERR_PTR on
failure, checked with IS_ERR() and propagated via PTR_ERR(). Similar to
platform_get_irq(), it can return -EPROBE_DEFER so move it early.

The pata-rb532-cf platform device (arch/mips/rb532/devices.c) provides a
single IORESOURCE_MEM window at the DEV1BASE chip-select, distinct from
the other RB532 chip-selects, so the region reservation now performed by
devm_platform_ioremap_resource() introduces no conflict. The mapped size
is unchanged. Drop the redundant error message, as
devm_platform_ioremap_resource() already logs on failure.

Built for MIPS (rb532_defconfig) with LLVM=1;
drivers/ata/pata_rb532_cf.o compiles cleanly.
