drivers: pva: Fix build for Linux v6.11

Browse Source 
In Linux v6.11, commit 1a251f52cfdc ("minmax: make generic MIN() and
MAX() macros available everywhere") causes the PVA driver build to fail
with the following error:

 include/uapi/linux/nvpva_ioctl.h:601: error: "MAX" redefined [-Werror]
 601 | #define MAX(a, b) ((a) > (b) ? (a) : (b))

Fix this by add guards around the definition of 'MAX' in the
nvpva_ioctl.h file.

Bug 4749580
