mailbox: Improve RISCV_SBI_MPXY_MBOX guidance

Browse source 
RISC-V SBI Message Proxy (MPXY) Mailbox support defaults to enabled, but
the help text states "If unsure say N".

Recommend enabling this driver, as it is a very critical RISC-V driver
providing mailbox channels to other drivers such as clock, system MSIs,
etc.
