Return code of clk_prepare_enable() is ignored in many places.
The patch adds error handling for all of them.

RC_TYPE is confusing and it's just the protocol. So rename it.

When an ir-spi is registered, you get this message.
rc rc0: Unspecified device as /devices/platform/soc/3f215080.spi/spi_master/spi32766/spi32766.128/rc/rc0
"Unspecified device" refers to input_name, which makes no sense for IR
TX only devices. So, rename to device_name.
Also make driver_name const char* so that no casts are needed anywhere.
Now ir-spi reports:
rc rc0: IR SPI as /devices/platform/soc/3f215080.spi/spi_master/spi32766/spi32766.128/rc/rc0

The driver type can be assigned immediately when an RC device
requests to the framework to allocate the device.
This is an 'enum rc_driver_type' data type and specifies whether
the device is a raw receiver or scancode receiver. The type will
be given as parameter to the rc_allocate_device device.
Change accordingly all the drivers calling rc_allocate_device()
so that the device type is specified during the rc device
allocation. Whenever the device type is not specified, it will be
set as RC_DRIVER_SCANCODE which was the default '0' value.

unknown and other are for IR protocols for which we have no decoder,
so the raw IR drivers have no chance of generating them. cec is not
an IR protocol.

This driver doesn't claim the IR transmitter to be wakeup source. It
even disables the clock and the IR during suspend-resume cycle.
This patch removes yet another misuse of IRQF_NO_SUSPEND.

devm_ioremap_resource() returns void __iomem *, so change 'base' definition
accordingly.

While not all archs have readl_relaxed, we need to add a hack at the
driver to allow it to COMPILE_TEST on all archs:

IR transmitter driver for Hisilicon hix5hd2 soc
By default all protocols are disabled.
For example nec decoder can be enabled by either
1. ir-keytable -p nec
2. echo nec > /sys/class/rc/rc0/protocols
