566a03a623 ahci: Improve error handling 
Check the error bits in the interrupt status register. According to the
AHCI 1.2 spec, "Interrupt sources that are disabled (‘0’) are still
reflected in the status registers.", so this should work even though
grub uses polling

This fixes the following problem on a Fujitsu E744 laptop:

Sometimes there is a very long delay (up to several minutes) when
booting from hard disk. It seems accessing the DVD drive (which has no
disk inserted) sometimes fails with some errors, which leads to each
access being stalled until the 20s timeout triggers. This seems to
happen when grub is trying to read filesystem/partition data.

The problem is that the command_issue bit that is checked in the loop is
only reset if the "HBA receives a FIS which clears the BSY, DRQ, and ERR
bits for the command", but the ERR bit is never cleared. Therefore
command_issue is never reset and grub waits for the timeout.

The relevant bit in our case is the Task File Error Status (TFES), which
is equivalent to the ERR bit 0 in tfd. But this patch also checks
the other error bits except for the "Interface non-fatal error status"
bit.

f4b1b48a83 disk/ahci.c: Use defines GRUB_AHCI_HBA_PORT_CMD_SPIN_UP and GRUB_AHCI_HBA_PORT_CMD_POWER_ON 
Instead of hard coding `2` and `4` use the macros defined already at the
top of the file. As a consequence, wrap the now too long line.

ca59c24bd0 disk/ahci.c: Add port number to port debug messages 
Currently, some messages cannot be mapped to the port they belong to as
the port number is missing from the output. So add `port: n` to the
debug messages.
