soc: fsl: qe: replace qe_io{read,write}* wrappers by generic io{read,write}*
Commit6ac9b61786
("soc: fsl: qe: introduce qe_io{read,write}* wrappers") added specific I/O accessors for qe because at that time ioread/iowrite functions were sub-optimal on powerpc/32 compared to the architecture specific in_/out_ IO accessors. But as ioread/iowrite accessors are now equivalent since commit894fa235eb
("powerpc: inline iomap accessors"), use them in order to allow removal of the qe specific ones. Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Signed-off-by: Li Yang <leoyang.li@nxp.com>
