Tom Lendacky 87d044096e crypto: ccp - Fix device IRQ counting by using platform_irq_count()
The ccp driver loops through the platform device resources array to get
the IRQ count for the device. With commit a1a2b7125e10 ("of/platform: Drop
static setup of IRQ resource from DT core"), the IRQ resources are no
longer stored in the platform device resource array. As a result, the IRQ
count is now always zero. This causes the driver to issue a second call to
platform_get_irq(), which fails if the IRQ count is really 1, causing the
loading of the driver to fail.

Replace looping through the resources array to count the number of IRQs
with a call to platform_irq_count().

Fixes: a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core")
