If the probe fails, we should use pm_runtime_disable() to balance
pm_runtime_enable().
Add missing pm_runtime_disable() for meson_spifc_probe.

Use devm_platform_ioremap_resource() to simplify the code a bit.
This is detected by coccinelle.

This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

The regmap_config struct may be const because it is not modified by the
driver and regmap_init() accepts pointer to const.

A couple of new CONFIG_PM_RUNTIME users have been added recently
in the SPI subsystem.
However, after commit b2b49ccbdd (PM: Kconfig: Set PM_RUNTIME if
PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so
#ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to
depend on CONFIG_PM.
Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under
drivers/spi/ (again).

This is a driver for the Amlogic Meson SPIFC (SPI flash controller),
which is one of the two SPI controllers available on the SoC. It
doesn't support DMA and has a 64-byte unified transmit/receive buffer.
The device is optimized for interfacing with SPI NOR memories and
allows the execution of standard operations such as read, page
program, sector erase, etc. in a simplified way, toggling a bit in a
dedicated register. The driver doesn't use those predefined commands
and relies only on custom transfers.
