Unbreak CPCAP driver, which has one more bit in the day counter
increasing the max. range from 2014 to 2058. The original commit
introducing the range limit was obviously wrong, since the driver
has only been written in 2017 (3 years after 14 bits would have
run out).

The CPCAP rtc is a 14bit day counter plus a 17bit seconds counter.
Note that this failed on Nov 10 2014 so it is very likely this driver as
never been used since.

At over 4000 #includes, <linux/platform_device.h> is the 9th most
#included header file in the Linux kernel. It does not need
<linux/mod_devicetable.h>, so drop that header and explicitly add
<linux/mod_devicetable.h> to source files that need it.
4146 #include <linux/platform_device.h>
After this patch, there are 225 files that use <linux/mod_devicetable.h>,
for a reduction of around 3900 times that <linux/mod_devicetable.h>
does not have to be read & parsed.
225 #include <linux/mod_devicetable.h>
This patch was build-tested on 20 different arch-es.
It also makes these drivers SubmitChecklist#1 compliant.

The RTC core is always calling rtc_valid_tm after the read_time callback.
It is not necessary to call it just before returning from the callback.

There's a funny typo where IRQ_NONE is used instead of IRQF_TRIGGER_NONE
for request_threaded_irq(). Let's fix it before it gets copied elsewhere.

We shouldn't kfree(rtc) because is devm_ managed memory. It leads to a
