Subject: [PATCH 28/29] hw/char/pl011: fix baud rate calculation mainline
 inclusion from mainline-v7.2.0-rc2 commit
 31cb769c317e0623cbe2a3e8da437b6cd7ddef9b category: bugfix

--------------------------------

The PL011 TRM says that "UARTIBRD = 0 is invalid and UARTFBRD is ignored
when this is the case". But the code looks at FBRD for the invalid case.
Fix this.
