spi: stm32: Print summary 'callbacks suppressed' message
[ Upstream commit 195583504be28df5d608a4677dd796117aea875f ]
The original fix "spi: stm32: Rate-limit the 'Communication suspended' message"
still leads to "stm32h7_spi_irq_thread: 1696 callbacks suppressed" spew in the
kernel log. Since this 'Communication suspended' message is a debug print, add
RATELIMIT_MSG_ON_RELEASE flag to inhibit the "callbacks suspended" part during
normal operation and only print summary at the end.
