[PATCH 1/3] mailbox: pcc: rename platform interrupt bit macro name

[Huisong Li <lihuisong@huawei.com>]

Currently, the name of platform interrupt bit macro, ACPI_PCCT_DOORBELL,
is not very appropriate. The doorbell is generally considered as an action
when send mailbox data. Actually, the macro value comes from Platform
Interrupt in Platform Communications Channel Global Flags. If the bit is
'1', it means that the platform is capable of generating an interrupt to
indicate completion of a command.
