Subject: [PATCH 2/5] clocksource/drivers/imx-tpm: drop IRQF_IRQPOLL

From: Peng Fan <peng.fan@....com>

Per the Documentation,
IRQF_IRQPOLL is used for polling (only the interrupt that is registered
first in a shared interrupt is considered for performance reasons)
The TPM timer is not sharing interrupt with others, and pass irqpoll
not make sense for i.MX platform.
