Есть вот такой массив

[
    0 => [
         'controller' => ['v1/user'],
         'role' => [1],
         'action' => ['read']
    ],
    1 => [
        'controller' => ['v1/user'],
        'role' => [1],
        'action' => ['create']
    ],
    2 => [
        'controller' => ['v1/user'],
        'role' => [1],
        'action' => ['update']
    ],
    3 => [
        'controller' => ['v1/user'],
        'role' => [2],
        'action' => ['read']
    ],
    4 => [
        'controller' => ['v1/user'],
        'role' => [2],
        'action' => ['create']
    ]
]
Нужно сделать такой

[
    0 => [
         'controller' => ['v1/user'],
         'role' => [1, 2],
         'action' => ['read']
    ],
    1 => [
        'controller' => ['v1/user'],
        'role' => [1, 2],
        'action' => ['create']
    ],
    2 => [
        'controller' => ['v1/user'],
        'role' => [1],
        'action' => ['update']
    ]
]
