ACPI: EC: Eliminate in_interrupt() usage

Browse source

advance_transaction() is using in_interrupt() to distinguish between
an invocation from the interrupt handler and an invocation from
another part of the stack.

This looks misleading because chains like

  acpi_update_all_gpes() -> acpi_ev_gpe_detect() ->
  acpi_ev_detect_gpe() -> acpi_ec_gpe_handler()

should probably also behave as if they were called from an interrupt
handler.

Replace in_interrupt() usage with a function parameter.

Set this parameter to `true' if invoked from an interrupt handler
(acpi_ec_gpe_handler() and acpi_ec_irq_handler()) and `false'
otherwise.
