HwmonTempMain: revert the type of bus and address back to uint64_t

In I546e967abae7c0fb9fca645867e3037046037647, the type of bus and
address in HwmonTempMain were updated to size_t.

However, in some systems using i3c, the device name is composed by bus
number and the provisioned ID [1]. The provisioned ID is a 48-bit value
(MIPI I3C Basic, v1.1.1, section 5.1.4.1.1), which is greater than the
range of size_t on e.g. 32-bit ARM platforms. Thus, reverting the type
back to uint64_t.

[1] Linux in-turn uses this Provisioned ID to identify the device, and
exposes the Provisioned ID in the device name:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/i3c/master.c?h=v6.6#n1521

Tested:
- added unit test passed.
- can read temperature of the i3c devices from our system.
