Subject: [PATCH] Platform: Library: Move mailbox_sw_reg_read64() from posix
 mailbox.h

Without this change testbench IPC4 build fails with copier with
implicit definition of the function. The mailbox_sw_reg_read64()
function should be there in the same platform library mailbox.h
header as the 32 bit version of similar function. The header
mailbox.h for all Intel platforms is organized similarly.

The argument type is changed to size_t from uint32_t to follow
other similar functions.
