Hi Andy,

Remove legacy-of-mm-gpiochip.h header file. The above mentioned
file provides an OF API that's deprecated. There is no agnostic
alternatives to it and we have to open code the logic which was
hidden behind of_mm_gpiochip_add_data(). Note, most of the GPIO
drivers are using their own labeling schemas and resource retrieval
that only a few may gain of the code deduplication, so whenever
alternative is appear we can move drivers again to use that one.
As a side effect this change fixes a potential memory leak on
an error path, if of_mm_gpiochip_add_data() fails.
Is there a reason for having done this change in cpm1_gpiochip_add16()
and cpm1_gpiochip_add32() [arch/powerpc/platform/8xx/cpm1.c] and not in
cpm2_gpiochip_add32() [arch/powerpc/sysdev/cpm_common.c] while all three
functions are called from cpm_gpio_probe()
[arch/powerpc/sysdev/cpm_gpio.c] ?
