mainboard: Format irq_tables.c

Run the command below to format the files `irq_tables.c` of (mostly AMD)
mainboards correctly with GNU indent 2.2.10.

```
$ git grep -l 'if (sum != pirq->checksum) {' | xargs indent -l
```

Fix up the following two checkpatch.pl errors manually.

```
ERROR: that open brace { should be on the previous line
#1219: FILE: src/mainboard/gigabyte/ga_2761gxdk/irq_tables.c:129:
+			uint8_t reg[8] =
+			    { 0x41, 0x42, 0x43, 0x44, 0x60, 0x61, 0x62, 0x63 };

ERROR: that open brace { should be on the previous line
#1221: FILE: src/mainboard/gigabyte/ga_2761gxdk/irq_tables.c:131:
+			uint8_t irq[8] =
+			    { 0x0A, 0X0B, 0X0, 0X0a, 0X0B, 0X05, 0X0, 0X07 };

```

This is needed, so that follow-up commits, fixing checkpatch.pl errors
and warnings, won’t run into conflicts with the git commit hooks, when
for example, spaces instead of tabs are used for indentation.
