Subject: spi: airoha: remove unnecessary restriction length
X-Git-Tag: v6.19-rc1~150^2~28^2~8

spi: airoha: remove unnecessary restriction length

The "length < 160" restriction is not needed because airoha_snand_write_data()
and airoha_snand_read_data() will properly handle data transfers above
SPI_MAX_TRANSFER_SIZE.
