ata: ahci: fix enum constants for gcc-13

gcc-13 slightly changes the type of constant expressions that are defined
in an enum, which triggers a compile time sanity check in libata:

linux/drivers/ata/libahci.c: In function 'ahci_led_store':
linux/include/linux/compiler_types.h:357:45: error: call to '__compiletime_assert_302' declared with attribute error: BUILD_BUG_ON failed: sizeof(_s) > sizeof(long)
357 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)

The new behavior is that sizeof() returns the same value for the
constant as it does for the enum type, which is generally more sensible
and consistent.

The problem in libata is that it contains a single enum definition for
lots of unrelated constants, some of which are large positive (unsigned)
integers like 0xffffffff, while others like (1<<31) are interpreted as
negative integers, and this forces the enum type to become 64 bit wide
even though most constants would still fit into a signed 32-bit 'int'.

Fix this by changing the entire enum definition to use BIT(x) in place
of (1<<x), which results in all values being seen as 'unsigned' and
fitting into an unsigned 32-bit type.
