As interrupts are Level-triggered,unless and until we deassert the register
the interrupts are generated which causes spurious interrupts unhandled.
Now we deasserted the interrupt at top half which solved the below
"nobody cared" warning.

We are currently using generic PSP Mailbox register for sending SHA
complete command to PSP but observe random arbitration issue during
PSP validation as MP0_C2PMSG_26_REG used by other kernel modules.
Use separate mailbox registers and doorbell mechanism to send SHA_DMA
complete command to PSP. This fixes such validation issues and added
flexibility for sending more ACP commands to PSP in future as new mbox
registers i.e MP0_C2PMSG_114_REG and MP0_C2PMSG_73_REG are dedicated
by PSP for ACP communications.

We are using PTE_GRP1 for DMA operations to load firmware binaries
but we are enabling PTE_GRP and flushing ATU cache much before in
probe callbacks. This can cause issue if we try to load firmware
runtime during system resume as probe callback will not be invoked
hence PTE_GRP will not be enabled. Moreover it makes more sense to
flush the cache after register configuration.
Move PTE group register configuration to acp-loader within pre_fw_run
callback to avoid such issue.

Add lock and unlock around ipc irq handling code using hw semaphore
register that exhibit special property for register read calls. As
host and DSP firmware uses few shared registers, there is a possible
race condition around those shared registers values. This lock ensure
synchronization between Firmware and host ipc interrupts.
