Given that this option enables generic code (which you reuse for RISC-V

Hi Ming,
I found a erofs issue after commit 07173c3ec276

it tries to merge more physical continuous pages in one iovec.
However it breaks the current erofs_read_raw_page logic since it uses

Use PTR_ERR_OR_ZERO rather than if(IS_ERR(...)) + PTR_ERR

With calling dev_pm_set_wake_irq() to set MXC_V2 RTC as wakeup source
for suspend, generic wake irq mechanism will automatically enable

which are ONLY for enabling/disabling irq wake can be removed, it
simplifies the code.
